It was a lot of fun and I wish I was better so I could play more of it. I kept accidentally resetting back to the first level while trying to beat the second. :(
It was that I went back through the barrier between one & two which sent me back to one - so more user error :D Although backtracking between levels could be interesting - some sort of speed-matters metroidvania
Oh, I didn't test backtracking at all! But I agree that it could be an interesting idea. I always like it when metroidvania games have unique abilities instead of standard dash and double jump so abilities related to speed could be fun.
