hi can you tell me which is the most comfortable controller for celeste I use a dualshock 4 but I find myself uncomfortable for the wavedash ... I was willing to try the one for the snes

The problem with SNES controllers is that they don't have an analog stick, which makes feathers easier... something like an 8bitdo might be better if you're comfortable with the SNES layout.

but I have never seen anyone use the analog stick ie I don't know if it is essential

Quite a few top level players play with only the analog stick and most controller players switch from D-pad to analog for feathers. However it is not required and feathers can be done on D-pad. It really just comes down to what you're most comfortable with.

so it would be more suitable than the xbox one? since the one from play station 4 makes my fingers ache after a few minutes

however I will buy and try the snes ones I will let you know on this forum if it was worth it

ok actually ds4 is better
