I noticed 10 minutes after we delivered that the harpoons do not reset correctly if you reset the game... now luckily this can be avoided by just running the program again, but I certainly face-palmed when I found out.
It should technically be such an easy fix as well! A shame that I missed this bug.
Also, its awesome to see people having fun with this =D.
The graphics on the menu screen should explain all the controls and gameplay objectives. but its understandable that the gamerules are a bit 'out there'. its troublesome to hear that the intro text isn't working for everybody though >.<
The unpredictable nature of a physics system, and our rather... 'simple' procedural level generation doesn't help with providing a consistent level of difficulty.
