I enjoyed the music and visuals together, had a strange but fun vibe. The controls were really slippery. After I unlocked jump I had trouble using it, it felt like the game was ignoring my inputs. I wish the game kept my upgrades on restart, since dying was so easy. Several of my deaths were due to getting trapped by a triangle.
The music was great, I really liked it. I think some refinement to the player controls and this will be pretty good
