Since I can tell everyone's so excited about this game,
here's level 1 completed.
Tell me what you think, anyone who bothers to watch it. After figuring out a bit about how the game works, it winds up being pretty fast.
You are able to keep your dash speed by staying in the air. I was going to test if having the space suit saves you from being killed by the damaging floor in 1-3, but then I found that if you jump on the first frame you land on it, you don't get hit.
I have managed to get partially inside up-right slopes in testing, but I get ejected pretty quickly back to the left. I have not yet tried up-left slopes. There may be applications.
edit: oh, uh. I used the Ninja Jajamaru: Ginga Daisakusen rom. It may work with the Squashed prototype as well, I haven't tested. If you have Squashed, the movie plays until the first slope of 2-1
