The movement is okay but due to me tapping or holding shift for sprinting windows did the sticky keys thing on me. I enjoyed holding on shift and tapping space to help with jumping, the timing of the walls and holes felt too random for how I was playing.
Took me a second to realize left mouse click activated a lot of the abilities and having that shield which was really helpful once I did. Double jump helped me reach the parts that were on some of the levels. While in the shop menu I assumed Esc would be the exit shop key but was easy enough to figure out the E key exits.
The upgrade shop screen felt understandable but could use some work with where the tool tip shows up.
