Gotta say, I'm a huge fan of the combo mechanic. Planning out my moves in advance felt really fun, and being able to chain moves was a big part of why. However, at some points there was, well, no way forward, with rocks spawning in such a way that I was unable to move far enough horizontally to get past them. Also, sometimes my move chains were too long, and I got caught by the wave before I was able to finish the turn. Aside from those minor issues, it's a really great experience!
