I can't seem to make it past the third jump (where the spike guy is up on a higher ledge). The mechanic of the first spike guy trying to chase you and then becoming a platform seems pretty cool though, and the idea of linking an extra life to a small minigame is very good for the theme.
One other thing that I mentioned to another jammer, typically when the movement does not require analogue control (i.e. pushing less moves less, pushing more moves more) it is a good idea to give the option for dpad use with these kinds of 2d platformer games on the controller. Thank you for at least giving the option for the controller though!
