It feels like a 3D twist on Super Hexagon, and definitely a good one! If I continue the parallel, I wouldn’t mind the speed going way up way faster, and the cursor could move more quickly for more a nervous gameplay. Dying and retrying is part of the fun in this kind of mastery game. :)
Good job on this entry, and damn good job on the journal in the game description, that’s a very interesting insight in your process!
