A few problems
- After you take the flying powerup, sometimes when it ends you fall right into a pit
- After losing a life, where you have lives remaining, sometimes the next life falls right into a pit
Both of these could be fixed by having one free jump directly after flight and directly after losing a life, perhaps giving the person a couple free seconds of standing on the bottom without dying. -Or- have him immediately spawn in the middle and immediately spawn a small cloud under him as well.
The 2x, 3x, 4x kill combos are messed up in a way. If you jump on more than one enemy AT THE SAME TIME it doesn't register it as upping the combo, so I jumped on two enemies at the same time, then another enemy (without landing and without jumping again), to get only the 2x combo rather than 3x which it should have awarded.
Jumping on 4 enemies AT THE SAME TIME should award the 4x kill combo, for example, but as-is it wouldn't. It would count as only a 1x combo. I understand the bones throws don't count towards the combos, but come on.
