As stated in my bio, I am studying at the games academy.
In my first semester, I teamed up with some friends and together, we created a 2D platformer that I am really proud of. In addition to running and jumping, you can attract and repell cristals at will. You will have to use that ability constantly if you want to grab every last coin and reach all level exits. There are 13 levels + tutorial + bonusstage.
