This is very good! the dash reminds me of a retro platformer about an alien astronaut or somethin'. Was supposed to be released many years ago but I think it disappeared, do you know anything about what happened with it?
Thats funny, to me it seems more restrictive than a traditional dash, cause with that you can land on different spots depending on when you start dashing. Here you can only stop against solid objects. Still, that doesn't mean its not worth pursuing, on the contrary. Almost all platformers have a dash nowadays, but something extreme like this? there is room to expand the concept for sure
