I just prove your game a it's nice :D. The controls are smoth and the concept is great, having only one minute to kill al the enemies is fun, and the "power level" mechanic that you need to kill the enemies in really interesting Nice work.
Here is ours, a 8-bit style rogue like where all the values are driven by the same number, you "life" so, the money that you collect, the attack that you have and other thing depend totally on that value. Have Fun!
