Thanks for your kind words! The timings in this jam game were a little off indeed. If you pushed the button too soon it would sometimes register as a fail when it really shouldn't, but it was too late when I realized this to fix it ^^
Dungeon Rummage - Origins, the game from which I derived this system is not going to have this problem :D
A game about the goblin brothers huh? I mean I tmight happen one day...
