Finally got around to finishing 3-stars on all the levels. Loved the game but I have a few notes:
- Some levels have basically what amounts to a forced death on the first time doing where you have to stop your momentum and switch direction - I don't particularly enjoy these trial-and-error sections, but I can see the idea of using the instant-momentum stop mechanic. This screenshot is an example of a situation like that - you will never see the spikes on the right wall coming and will pretty much 100% die to them the first couple times playing the level:

- I think there's a bug with the Vines mechanic, it seems like they all share the same cooldown or something. I can't grab on a new vine if the previous one is still in the gray circle "cooldown" animation.
- Dustforce has checkpoints that make the level essentially not count for scoring if you use them (you have to "enable checkpoints" in options), just something to consider adding for long levels to make practicing certain sections easier (only if a safe platform exists to actually have the checkpoint on).
- The game made me slightly motion sick which is something that literally never happened to me in any game before, I don't know why - if it's the background parallax, camera following, color palette I chose, or whatever - but it's a shame that I can't play it for long sessions when I like it so much.
For the record: I played with keyboard and had no problems - I always feel like these kind of games are actually easier on keyboard, many Dustforce experts recommend keyboards too.
Wishing you the best and looking forward to the full release!
