I've been addicted to this game for the past few days.
What really made me keep playing was wanting to see what characters were in the next level.
It was a bit disappointing to see characters re-used on the last level though (Neo, Y-turtle), It feels like the streak of creativity was all for nothing.
But still, I really enjoyed it so I'm giving it 5 stars,
There were a few problems that could do with some fixing,
one being with the ranged cats, if you drop down and attack an fox below, if the cat is at the back, it could get stuck there, shooting aimlessly, causing you to restart your game.
Could use with a leveling up tutorial (like one panel saying you can level up).
Loved it and want more!
