Under construction.
Not a bad start at a platform game 
Could do with more to the gameplay than just making Jumps. Switches to move platforms, monsters to avoid etc.
Don’t know if there is a storyline, like you’re collecting powercells for your spaceship.
If I was taking this further, I’d think of a storyline, like your spaceship has crashed, and you have to collect things to repair it. Once repaired it launches/crashes on the next level. Think of some puzzles/style for each level, decide on what the main character (like a robot) and monsters are.
Could have the start of an appealing game.
I like it! Controls felt a little slippery to me but I like the concept and would like to see later versions if any are planned.
