deep down

by Jan Peter (jpdev) - 48 Hour Compo Entry

The small yellow submarine with it's heroic crew is on a deep sea mission. Far below the surface it has to defend itself against an onslaught of vicious sharks and later on other submarines.

Use Cursor-Up & Cursor-Down (or "W" and "S") to move the sub
Use Space to shoot torpedoes.

This game is pure JavaScript - it should be playable in all HTML5-browsers. (I have tested IE 11, latest Firefox and latest Chrome)

The sprites are drawn with pencil on paper and then edited and colored in gimp and arranged with

It's build with the help of the gaming framework phaser (

The sound effects are created with sfxr (sound effect generator by DrPetter).

The background music is created with autotracker-bottomup (#ultimate audio experience by GreaseMonkey).

I like how the sharks just get bigger and bigger. . . :)

I like the look and feel of this.

Good game but there isn't an ammo counter, so if I go straight in a line and shoot torpedoes I won't die. Improve it.
Good game.

Thank you all for the feedback.

to Recon:
- there is now a score, if you shoot and hit nothing you are punished
- there are now rocks so you can't stay in a straight line on the lower half of the screen
- there will be enemy submarines on the top half of the screen... (not yet though)

Is a cool little concept :) Yet I believe it lacks some gameplay and art. If you were to add extra ways to gather points that'd be cool!

Apr 27, 2014 @ 3:23pm

Okay, I am done now.
Latest features: enemy submarine and a completion screen

Enjoy :)

Nice, cook art. and Controls were just floaty enough.

The controls are floaty in a good way: it feels like you're steering a submarine. Blowing up sharks is very satisfying.

Neat, who doesn't like blowing up sharks? The music was really nice too!

Love it! With the slow torpedoes, hitting a shark is just terribly satisfying!

Solid game. Found it a bit slow but nice work overall :)

I enjoyed this game overall. I thought that the sub was a bit hard to move, but then again anything underwater should be.

If I were more educated on animal rights, I'd have some serious concerns about this game.

Apr 28, 2014 @ 4:11am

Really fun, the movement and torpedo shooting feels just right!

Love that you drew the art on paper. Quite fun.

Whoa, full screen loading bar..! That's kinda cool...
+1 for sharks, +1 for EXPLOSIONS, and +1 for shark gibs..! End of game stats are always awesome...
I like how the sub gets damaged as you ram sharks...

Really nice cartoony look. Good job on the controls as well - it feels like you're under water.

Nice but where are the other submarines to shoot ?

Apr 28, 2014 @ 11:39am

Thanks for all the feedback.

monaarc: After ten shark-kills you get one submarine, then it's ten shark-kills again.

It's nice to come across sounds made with sfxr that are NOT a pain to the ears. Thank you :)

I love that scrolling algae! The controls are very smooth.

Good sound design. The sharks exploding is satisfying. The gameplay is a little sluggish, but it's a finished game. I also liked the stats at the end - that could go somewhere a la jetpackjoy ride missions.

I like the music! Nice graphics.
I also like the summary at the end with all the achievements.

But a health meter for my submarine would be great and some powerups or something.

Gaspard_ says ...
Apr 29, 2014 @ 1:48pm

I liked the summary at the end, I was wondering: is it possible to get a positive score?
I think it could be easily improved, but for 48 hours this is quite good.

This game is very fun to play, you did a great job on it. The difficulty is increasing just as it should, the inertia of the submarine adds difficulty. The graphics/audio are pleasant. Kept me entertained for quite a long time :)

Apr 29, 2014 @ 8:11pm

Thanks again for the comments.

@Gaspard: yes, positive score is no problem, you get -5 for each shot you miss, just don't miss and you're golden ;)

Apr 29, 2014 @ 8:35pm

Nice shmup. I would have expected the torpedos to be launched in the direction of the submarine ( not always horizontally ). Is that a choice?

Pretty cool game.
I like the little detail with how the submarine gets banged up!

Really loved this one - well done parallax. Graphics are dope :)

rojo says ...
May 4, 2014 @ 6:10am

Not bad. The sub movement felt pretty smooth, and the parallaxing looked nice.

This is a fun little game. It doesn't break any barriers, but it's a run romp I can come back to now and then. And I must admit that the controls & speeds of everything feel just right, as does the rate at which the sharks get bigger and bigger. Good work!

Really good fun. I love the art, with the seaweed layer up close and the sub movement feels good. Audio was cool too.

Good job, liked how the movement/controls are working.

loved the way the sub controlled, it felt like it was really under water, great work!
