celeste the core but made in 72 hours
I feel like the jump is really random, especially when climbing walls. My jump goes up a fourth of my normal jump when I'm jumping from a wall, and the dash just teleports me so it's really difficult to super dash. Why even have the function to backtrack if you just need to do the whole room again to progress again. Many times I felt like I had an unfair amount of time because I don't know this game in and out, and all of the best strategies, etc. The music stopped after a while, and doesn't loop. I think it's too many controls for new people, mainly for those who hasn't played Celeste at all. The stamina bubbles doesn't respawn, neither does the falling blocks. Which makes attempts really long because there is no restart button.
I see where you're trying to go with this, but a really good thing to keep in mind is one mechanic at a time.
I'm glad I played Celeste with a controller
