VERY cool, I really liked this. The graphics and polish on this are amazing, it played really well, and I felt like there was a lot more to it than I got to explore in one playthrough (by virtue of having avoided some obstacles.)
The levels and threats all look amazing and feel like great contributions to the overall challenge and liveliness of the game. I didn't continue playing after my first game over, but encountered no issues at all. Would have loved to have some music in it to really complete the experience, and my brain got z and x mixed up often enough to make an accidental dash a bit frustrating, but that's really on me!
