I truly want to attain the good end, but I stuck at the final stage of the cat challenge...I asked my partner to try and he also stuck at the same stage. We were expecting 3 waves of enemies, but finally failed in the 4th wave. Missing one ball leads to game end...I hope the cat can move faster or allowing 1 to 3 misses, something like a shield protecting the door and the shield will be destroyed when the cat missed a number of balls. Or like others said, a checkpoint between waves. Other than the game difficulties, everything is nice and polished, graphics are very presentable and the music suits the theme. Great job!
