Fun game with fun mechanics, but it does commit some platformer sins
- Physics/movement are inconsistent. In level 005 in particular - I jump up, run to the left and die sometimes? Sometimes I will hit my head on the ceiling spikes, but sometimes I won't
- Movement felt slippery overall, I had to make moves ahead of time because it took a bit too long to stop and turn, especially with spikes all over the place and having to do frame perfect input. It felt like muscle memory was the only way to beat it
- Could use some more lenient jumping rules, particularly Wile E. Coyote jump (allow jumping for a few frames after the player is off the edge) and let the players start holding jump again mid-air so that when they touch the ground, she jumps again automatically
- You might be planning this already, but I think Hard Mode should be an unlockable. I made the mistake of doing it first and got demolished because I didn't know the levels and going back to square 1 was really frustrating. Easy Mode was alright. For Hard Mode, consider not starting the timer until the player moves, so they have the time to acknowledge what the level is and plan what to do
- Running through buttons that are already pressed should refresh them. I had a situation in one level (maybe 008) where I ran through a button, died, respawned, ran through the button again before the timer ran out, ran through the door it was keeping open, the time ran out, door spawned on me and telefragged me
- On 002 if you hold right while jumping down the bottom of the screen, you will get stuck on an invisible platform. Happened consistently
But honestly, these are mostly personal nitpicks and even with the current mechanics and physics, you have a good game here. As someone who 100%'d Super Meat Boy and End is Nigh, I would probably buy and 100% this game
