Actually, the "out of control" idea was that you never know when exactly you will explode because the time between explosions is randomised within some parameters. Since we ran out of time the proper indicator before explosion wasn't implemented sadly. Same for level design, this one is just for testing. The coin respawn was a last minute thought since we only had one level so you can play it a bit longer. Thanks for playing the game (also it will get updates after the end of voting).
