Short and sweet ! I ended up not struggling that much since i'm used to playing difficult (im)precision games, but the level 9 still had me struggle for a bit i have to admit!
(i really liked how i could sacrifice health by crashing into the walls to offset the timings of the long shocks, no clue if that was intended but it worked well for me ^^)
The music/ambience sounds fits amazingly well with the simple spritework, the background just being a scrolling/changing noise texture is just so smart too ! (i need to experiment more with noise someday because it looks so good in this!)
The vibes are just top tier, awesome game !! Loved playing through it ^v^
And as someone else said, the cover is absolutely gorgeous!
