Broken Cave Robot

by YMM - Competition Entry


The in-game map is saved every time you play. So the next time you play you continue with the same map you drew last time. It is also exported to a BMP file in the same folder as the game after each play.


I've fixed some bugs since the deadline, but in the interest of following the competition rules, the version you download from this site does not have those fixes (it is the original 48h version). Rate me based on this version, but if you want the newest version you can find it on my site ( Known bugs in the 48h version are (all fixed in the version on my site):
-One obscure hard-to-reach exit in one room doesn't work properly.
-If time runs out when you have your map open, the game crashes.
-Some users get 'Unexpected Error' and crash on startup :(
-Sometimes crashes if the corpse exits some rooms.


-Game Maker 7.0


- This game uses some video rendering capabilities that may not be compatible with various graphics cards. If
the game does not show up properly, restarting your PC may solve the problem.

- The game may crash if your screensaver comes on while playing, or you try to set your PC's resolution while the game is running.

Very cool game. Reminds me of a feeling in some oldschool games, like on spectrum..

doohan says ...

A really nice game. Music is great. Fun to explore the cavern and find all the power ups.

badlydrawnrod says ...

I liked the lo-tech art style and lighting, and the map was a neat touch.

jolle says ...

This is really good. Great ambience and fun to play.

I'd really would have prefered auto mapping, though. And I'm generally against games with time limits.

ajdef3 says ...

Great map and lighting system. Awesome job. :)

Hempuli says ...

I really enjoyed this! Great Metroidish feeling.

Almost says ...

Great game. You are given a very vague objective, and pressure to get it done. Many little style things are done right: for example, not one hit kill, and not health bar, but rather two hits in short time. The art style with lights etc is great.

Objelisks says ...

Awesome game. The lighting was really good. I think it would have been more fun to not have a time limit, though. But the map helps with that.

Endurion says ...

Awesome game.

Just some small things that I don't like personally: Auto-map with writeability (Ultima Underworld style) ;)
And there's that one spot where I died twice, hit a bird, fall onto spikes and fall onto spikes again. Instant end.

adam_smasher says ...

Beautiful little game.

I'm not sure about the manual mapping, though - it's great in games with less complex map structures, but here it's a bit overwhelming.

fydo says ...

Nice work :)
The robot is cute, and I had fun.

Terry says ...

This is my favourite game from the weekend. I loved the design ballsyness of encouraging the player to keep a map rather than just implementing a basic automap; I kept one on paper and got pretty far with it.

Loved the soundtrack too!

dessgeega says ...

i like the idea of a map that persists across multiple plays, so that although i may play and run out of time a bunch of times, i'll eventually put together a complete enough map to find my way through. except that this game's caverns don't really seem very interesting to map, and i wasn't really inspired to replay it.

philomory says ...

This game is pretty fantastic. I have no idea if it's actually possible to win, or if you're just collecting stuff. But I think I'll keep trying to find a way out of the cave.

noonat says ...

Great game. Loved the music, loved the dialogue with the player, loved the retro graphics. I thought the manual map was a bit much, though.

erik says ...

Wow, this is addictive. It's really eating up a lot of my time.

It's so strange to have this drive to upgrade your character, yet be faced with the inevitability of the time limit. It makes me sad that I don't think I will ever find a battery upgrade or an exit.

The in game mapping tool is kind of interesting, but I don't see any advantages over pen and paper.

The graphics were quite blurry, and the lights a bit flickery. The art was nice, but it didn't seem to quite set the same tone as the gameplay and sound. The sound is very well done.

Excellent job overall. I really hope that I'm going to find a satisfying end somewhere in the game, but I don't think I will.

HybridMind says ...

I had a great time playing this.. very stressful to near the end with the time limit running out! I had no idea how near I was but I had managed to upgrade my flashlight like 3-4 times. I loved the flashlight powerup concept. The graphic style was done very well and the controls, movements, and powerups were nicely done as well. There were a variety of hazards and obstacles to overcome using the various powerups as well. Great job and congrats on your first LD!

Entar says ...

Great music, cool atmosphere and mood. Very well done, though I didn't really think the manual drawing mechanic fit quite right... I dunno.

Sparky says ...

This is really nicely executed. The 'two hits' rule is a nice bit of design. I like how open ended this is. It's very free, yet I'm motivated to play and explore quite effectively.

Thanks for making this!

agj says ...

Wow, game's harsh. But it makes me think of a game like this, but without the possibility of dying; it would be a cartography game, wouldn't it.

sirGustav says ...

great! never used the map-drawing though as I usually just walk blindly towards my doom :)

ondrew says ...

This is really the full package. Cool graphics and music, really fun gameplay, lot's of content and on top of that all a story too.

I just miss a tiny little checkpoint somewhere :)

Problem Machine says ...

Okay I was able to play the non-compo version, compo version crashed. I really like the atmosphere of it, and the music was absolutely fantastic. Unfortunately I'm kind of just not willing to draw my own map, so I'm trying to just remember things as I go.

localcoder says ...

This was great. The whole game feels friendly and kind of daydreamy - like at the start, when you wonder whether you have lost your memory or if you are just a newborn

The map idea is really cool - especially how it persists between games. But the drawing tool was too frustrating for me. The colours weren't clear, it was hard to draw clean lines and I didn't know where to start on the page or how big I should draw things.

Apart from that, it's great fun to explore the caverns, jump on enemies and listen to the guitar :)

SpaceManiac says ...

An awesome type of game!
