Thanks for the feedback, as somebody who has beaten and speedruns celeste themselves, I thought that atleast 90% of people who play platformers use a controller, but tbh I have nothing to back up this thought. The thing is a few jams ago I got a few comments that told me the keyboard controls were pretty bad, so since then I've always written in the description or at the start of the game that you should use a controller. I definitely understand your criticism, but I feel like most people who play these games are more used to playing platformers with controller but again, I might be wrong about that.
