One Jump

by Xanjos - 48 Hour Compo Entry

My 2nd Ludum Dare entry and my first for the 48hr compo.

The aim of the game is to just reach the exit. However, you only get one jump per level (hence the title and gimmick for the theme)

Don't mind the crude graphics (I can't really draw) and some things are really buggy (like moving platforms). Also, I'm really bad at making platformer levels.

UPDATE: I've added standalone versions for Windows, Mac and Linux. I had to slightly readjust the position of some objects as they seemed strangely out of place compared to the original web version (I highly recommend that you try playing that version first before downloading any of the standalone version instead). Also, since I don't have a Mac or Linux machine, if anyone can download and test those versions and see that there's no problems that would be great.

Game Instructions:

Arrows/A and D to move. Spacebar to jump. R to restart the level.

Tools Used:

Got stuck in the third level, replay button would not hurt. Overall kind dull but definietly a game :)

@postmodestie: You can press R to restart the level if that's what you're looking for. Don't know why I forgot to mention it in the first place.

Despite some problems with collision and stuff, some levels are interesting. Sure thing “one jump” is a gimmick, but it is a good constraint to exercise on level design. Keep up working, man!

It's kinda funny how the player character sticks to walls. It allows for a bit of cheating. Good take on the theme.

The level I liked the best was the one before the final level (level 3?). It was much more about puzzle solving than trying to avoid the spikes.

There are some collision problems, but the concept is nice!

Really good concept. Graphics could have been better though.

Found it pretty difficult to jump, not sure if thats due to collision problems or just timing, nice idea though :)

A bit buggy with collision and movement, but pretty enjoyable. Having to use the mouse for buttons is a bit bothersome, too.

Made it to the end, the controls are very rough, especially the jump. Collision are a little bit messy. This is a nice try , tho'. Keep improving.

Very smart implementation of the theme. Your puzzles are well thought out if a little frustrating.

Well put together, but having to move my hands back to the mouse to click the buttons was really frustrating. With what should be a boring mechanic, you did a good job coming up with twists to keep it fresh.

I liked this game! I thought the physics of the player were really good, and there were a good variety of tricky platforming tropes on display - falling and moving platforms, sticking to walls, switch plates etc etc. The difficult curve could have been a little smoother but given the time available this is pretty complete and really had that "just one more try" thing. Music would have added a lot, and perhaps some particles?

Very difficult to move on moving platform!

Thanks for the mostly positive comments guys. I've actually got time to clarify a few things:

Regarding the wall sticking, that was unintentional.

Jumping is a bit weird as you have to build some momentum (i.e. make a run) to jump further.

@jimmypaulin: I did create some background music but I ended up deleting it because I couldn't get it to loop properly in Unity.

@van noctar: The moving platforms are extremely buggy as I couldn't get the player to "stick" to the platform properly as it moves so you have to move with the platform instead (which is rather weird).

Weird physics sometimes here :)

A lot better than you give yourself credit for. The idea is innovative, and the gameplay is pretty challenging without being unfair or broken. The levels look well-designed to me.

My only issue is that it's a bit hard to control your character (I had to retry the level where you move the brown block quite a few times, just because it was so easy to slide over the edge). Also, once I got to the level with the disappearing floor, I couldn't progress any further: I couldn't go to the right, but if I jumped down the pit I just bobbed up and down without dying or progressing. Not sure whether that was a bug or there were no more levels.

Still, quite an entertaining game.

@Christina: Which level was this? The bobbing thing is probably due to the code that stops the player going off camera (since it works on all sides) and also, the fall zone trigger probably needs to be adjusted for that level too.

Dec 25, 2013 @ 1:11pm

I don't know which number level it is, but it's a fair bit into the game. It's the one that has a narrow lava pit at the start, then a section of the floor near the end of the level that falls away when you step on it (that section is visibly separate from the rest of the floor).

Hope that helps.

Some glitches with collision and movement. The leveldesign was nice considering you can only jump once but it is probably not the best idea for a platformer. I missed a button to go to the next level.

Good idea, the controlls are a bit floaty though. I like the wall grabbing, but i dont know if that was intentional or not. i think you could take this in a number of directions for levels if you can tighten the controlls up a bit.

As you play with the keyboard it would be nice to be able to retry the level using the keyboard also.
Also, if you jump when you are right next to a wall, it doesn't jump

The concept is very interesting and nice take on the theme. The controls need to be tightened, but the game idea could evolve to something great.

A bit confusing, but great game :)

Dec 29, 2013 @ 9:48pm

The level with the drop down, jittery moving platform, and the door inbetween the spikes is where i got to before it wasn't fun. (too hard) i need friction to land on that platform. lol Amusing. nice.

Great job! Loved the puzzles that arised from only being able to jump once. Awesome level design.

Interesting level design, well done. Too bad the physics of it all are very hard to control, making it a bit frustrating.

Pitzik4 says ...

I eventually gave up on the level with the "chimney" of spikes leading down to the door because for all I knew I would have to line myself up pixel-perfectly to get down it. It's too bad, because it seemed like the levels were starting to get interesting.

Needing to use the mouse was kind of annoying. If this game was developed further, it would be an interesting puzzle platformer.

Jan 4, 2014 @ 4:15pm

Your interpretation of the theme was original, although I would have liked to see more polish even if it's a 48h entry. (like no wall sticking or having to use the mouse to retry a level, more visual flair, etc.)

Vi-King Games says ...

Good take on the theme, and fun level design. However, the physics/collisions/controls/whatever feel unnatural, moving platforms are very hard to stay on, and there's a wall-grabbing glitch that makes it easy to cheat (but also kinda fun, maybe make it a game mechanic for a new game? ;)). Maybe the graphics could be more developed too, but I don't really mind.

Zerkruemler says ...

Cool idea, and good 'tutorial', but somehow unexact controls. I had fun the first few levels, but was not able to jump where i have to push the brown 'colleague' into the spikes. Maybe a bug? I don't really mind the poor graphics and sound, but the controls are important, they should work flawless.
Keep on the good work.

Only ran into anything buggy once or twice. Nice job.

Interesting mechanics. Well execution. I didn't like the idea to press the replay and main menu buttons with the mouse when you play with both hands in the keyboard. Congrats.

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crash or win condition bugs after the deadline (in a sense, like “porting” to support more players). We also allow “typo” bugs.
