Celeste is an impressive game, and if they made it in 124 it could have had much better graphics than those, but of course, I understand that with the speed of being in a game jam it is impossible to dedicate so much to it.
Draw conclusions, the pixel art that I do is in 64 x 64 and you see that they are of very high quality, now imagine in 128 x 128 what I can achieve. The level of detail is greater, but of course making these animations takes more work, which we were talking about in other posts recently.
This game is really good and I love it.
