Aaargh I can't get more than 300 points!
Cool game (pun intended).
I would really have liked for it to support a controller input to, never did have a GameBoy but having a nav-cross and a jump button should be OK shouldn't it?
For the snowy platforms I think it would feel nicer if you got a little fraction of a second longer before you had to jump.
The fact that you can be more or less entirely outside the screen and still be alive was at times surprising.
There was something else about the controls that didn't feel 112% perfect, but I couldn't really pinpoint what it was (maybe something with grace-period of being grounded and allowing jump or even forecasting 'about to be grounded') that made the jumping a little annoying.
But, as per always: super well made!
