Loved this proof of concept! my only feedback is to maybe incorporate more than one solution for better replay value. I also think including new effects like Animal tf to help build upon OPP.
Also could add unlockable rewards for the Character Creator, like how OPP had rewards for how high your score was.
(I am hoping clown, goth, cow and honey get included in the future since I loved how they were incorporated in OPP)
But I am very much looking forward for what's next regardless! keep up the good work!
