yeeeeeeep! Dev here... my bad :D 

It's not a bug, it's a feature /j

The cat is immortal bc its chaos keeps it going- it simply cannot be vanquished within this mortal realm 

Thank you :P

Hi! The cat was dark blue to mimic the way black fur used to be done in cartoons- such as the cat in Sailor Moon being a dark purple. I found the black to be too harsh with the background. The spawning of the tiles was just an issue I ended up not having time to fix, as it was an animation loop

Thank you! We didn't end up having time to fix it but we had a couple of other animations too ^w^
