that's my type of game! I really like hard platformers, and not too long ago I finished the White Palace in Hollow Knight—this really reminded me of it.
It took me a while to get the hang of the controls, but once I did, I was locked in. However, I think the input timer for moves could be more forgiving. Sometimes it felt like I pressed the buttons at the right time, but the game didn't register it. After playing for a while, I quit out of frustration, but I might come back to finish it later. I'll let you know if I do! :D
The game looks unique and cool. The music really helped build the atmosphere, and the variable jump height and camera movement were nice touches.
I'd suggest removing the player's acceleration and deceleration, as that made jumping onto small platforms feel harder than it should be , also some sfxs would make the game feel more alive .
But overall, a great submission!!
