While I wished I could continue, a few things had me stop from the first level.
First, the button prompts are horrible for WASD controls, I can't press X while using WASD.
Bomb's collisions are huge, and I took damage from it without even touching it.
Restarting from the beginning every time is a bit annoying, after collecting a coin the first time, I quit collecting them anymore.
Having to use the mouse to restart is a bad idea for a game that doesn't use the mouse, making restarting the level even more tedious.
I'm not trying to say this is a bad game, I think it's pretty good, I just wished there were a bit easier and having a faster restarting method, I am not bad at platformers at all, this is just difficult because of the buttons positions and the energy it takes to restart a level.
