real good
i think its really good. its hard but addicting i finished it on beginner i only have 2 minor complaints:
1- when u die your not invulnerable for logn enouph.
2- time bonus should be more balanced on beginner some lvl where impossible to have more than 0 time bonus
o yea maybe being able to upgrade your character instead of just gaining new abilities like you could upgrade speed, acceleration, recovery time after being hit and stuff.
o i forgot one last thing the turtle thinghie was overpower all you gotta do once you get it is taking baby steps throught all the lvls and convert all the red coins you see.
i give 9/10 4/5
