Love the art direction here! The purples and soft glows work together with the music to create a chill, relaxed vibe. The gameplay itself seems a lot more hardcore. The levels go on for a bit, and so getting sent all the way back to the start off one hit is quite punishing. I also found the hit boxes to extend far outside the visible boundaries of the bat. I ultimately had to tap out on level 3 where there seems to be a really tight gap right at the intersection of a snake, fish, and ceiling worm. Tightening up the hit box or keeping checkpoints along the way (bat perches maybe?) would go a long way toward approachability.
That said, the sound-based auras of light around the various obstacles is a really cool idea. This is a nice substitute for the echo location ability while it is charging up.
