It's decent but has many flaws. For one, there should be zero delay when restarting a level. The pause animation takes a while and so does restarting the level and even after that you gotta wait on the "ready" screen. Also jumping feels weird. Holding down the button while mid air and landing on a platform counting as a jump simply does not exist in this game. I like the levels so there's that.
Also I just beat all the lvls with zero deaths but where tf is my medal..?
