Not gonna lie, it was hard to finish a "normal" level by myelf, just because i was constantly mistaking the commands for each sphere hahaha
But the game is really cool ! The amtosphere and the graphics are so sleek, it goes really well with the audio. I would just add a little sound when you get knocked by one of those luminous spheres, but nothing to overwhelming, just something to tie the audio and the gameplay.
Overall i really enjoyed it and i'll definitely try it with a player 2 when i'll have the occasion !
