Don't click the orange cat (you). Click green flag to start. Click Thief Cat to get your crystals back. (Thief Cat stole them!!!) It has a secret ending, DON'T tell in the comments how to get it (especially in my profile).

It's kind of hard for me 'cause I have to move my mouse a lot and he stole too much crystals. (I meant to make it like that.) You can comment if you got all your crystals back. I took so long on this so I hope you enjoy! Use arrow keys or WASD to move.(I feel like you don't even need to move!!! XD)
