It's poorly designed imo, movement and jump was weird/off, besides that right at the start i dug holes under MC's feet so he left the screen and there was no other visible way to bring him back so i had to refresh the browser. If you'll add more coherent and failsafe design (for example character not getting stuck at places in a way that u have to restart the game, for example character being able to atleast jump high enough to jump up from out of the screen hole) aswell as tighter controls, i might be willing to give this another chance, for now that's all think about it.
