Hey, I'm sorry about that, I didn't expect someone would actually play it :D. It's not a finished game, but I wanted to quickly wrap it up..
Anyway, the cockroaches are coal, and the sleeping bag is coal storage :D but you figured out that one nicely.
On the top, you have pointy cockroaches that are shells, which you need to load into the guns to shoot at the enemy.. after you destroy it, that's it.
Don't the afraid, the enemy won't bite.
You need to grab them by holding "G". press C to see all the controls.. after you hold G to carry ammo / coal, you'll be able to drop it where it needs to go..
When you drop ammo on guns (straws), they will load up with a green indicator. Later on you will be able to press E to shoot.
Also, the submarine only moves when enough coal is loaded, so I suggest you load 2 or 3 first.. then try moving with "i, j, k, l" to avoid having to manually control the steering :D
