To defeat the level with the bouncing guy and the coins at the beginning, you have to first blow his head up 4(?) times and bounce up. From there, drop down to the lower ledge and jump on the third coin. Every other coin is solid.
12 minutes, mostly spent on the last level and the one where you have to move the pictures to make a cow. Both games I do not know a key for and constantly torment me.
The rules boil down to "there must be input (provided by the player) and output (provided by the game)" In this game, the input is mostly pressing the space bar, but there is also the Pong, Table Tennis, Ice Hockey, and Thing I Can't Remember The Name Of.
