Wow, thanks for the long review. :D
Well, the spikes are usually there to instant kill, for most platformers, but I made it fixed to 100 and the maximum health on late game will be 300, so it's the one I shouldn't make easier imo, since I already took it in my mind that the player will have 3 max chances to get hit by spikes. :p
And... for the Wall Jump, I think I will make it a bit easier to wall jump next time. :)
Anyway, thanks again for always reacting to my game releases here and ~there in the yoyogames forums, Torball. ^,^
