Thanks for the feedback! Loved your puzzle game!
Yeah I agree, there should definitely at least be checkpoints, I'm currently putting together a patch with controller support, so (maybe) I could upload a seperate build or make a seperate page with checkpoints. I dunno if it would change the game too much or count as QoL (might need to ask) but I 100% agree that the game should've been a bit more forgiving, and a bit easier on the difficulty curve. I also had some ideas to improve the leniency of the dash that I didn't have time to implement (thanks for the screencap, the dash *is* still annoying to deal with even with the current buffer, I felt your pain)
Was happy to see it worked for people who already play a lot of platformers but I can understand it's hard for those just getting into it.
