First week using Unity and here's the first prototype of a 2d platformer game.

First html on repl as well (I normally code python discord bots)
The game has a few known bugs, score does not regenerate.
To climb walls use space/up + the arrow key to move onto the wall.
Also, beware there is a bug where some enemies make you go at crouch speed (don't get too close).
