Cool game. I didn't know I had to back track once I got my double jump at first. Kinda a homage to Castlevania SOTN which I liked. The game is quite challenging as I had to quite after a dozen or so attempts at the bottom level with the jumps that are like 7 in a row. I think an average player can only do 3-4 hard jumps before getting frustrated. I wished there were more ways to show the player what is happening e.g. death animation, particles, sound effects. Also, there are some videos about platformer player camera that I recommend watching. One trick is to let the players see some of the level that's underneath them when falling so they can aim their character a bit better. You can balance that out by making the jumps a little more challenging. I see potential in this game and I hope you keep working on it. Thanks!
