9/10, some things are hard to notice (it took me a while to realize that there are some pointers to enemies etc, not sure if necessarily a bad thing), there's this bug that if you are in water and you swim against the purple wall you bounce back and down, making it possibly to go down really far, not sure if you noticed that.
Generally a very good game, liked it a lot, great movement, awesome atmosphere, great aesthetics. Ori and the Blind Forest in 80s sci fi style.
I feel some levels at the end of region (Alpha, Beta, Gamma) should be longer to better close the region and to sum up all the new mechanics (see Ori and the Blind Forest, I think that game does that very good) and Towers feel like they are "boss fight" but turns out they are pretty short too.
Don't get me wrong, I REALLY liked this game, but you can make it even better! (if you are still working on it, if not you can make better next game)
