The game treads a balance between fun/challenging and frustrating, and for the most part stays in the former. The audience definitely skews towards more skilled players looking for a platforming challenge, and leaves little for players like myself who need git-gud. Checkpoints helped with this, but maybe an even easier introductory level for peasants like me would have been appreciated.
The W key seemed to be dash instead of space like the in-game instructions suggested, and while I remembered this, i did find myself expecting to jump when pressing W and I think that was the cause of my inability to play much of even the easier stuff.
In any case, the music is funky and the graphics are generally good but a bit more polish on that front would have been nice. Still an enjoyable game for the right audience with heaps of content in terms of levels etc, so well done.
