I attached a picture of the controls. Some things like the glider, dash, jetpack and swing/grappling hook won't work till you acquire the ability.
The game should tell you as you are playing what controls what for the most part though. The first two levels aren't really helpful right now, but it starts explaining how to play after that.
I'll push an update out next week and I'll try to get the control shot I attached into the game through the menu. I know right now it doesn't really work.
Also, if for some reason your cursor isn't visible or accessible you should be able to just hit Escape or Start again and it should come back.
Hope this helps and thanks for checking out the game and providing feedback!
