Its a very cute simple platforming game. Their were times where the double jump didnt work (wasnt responsive) but that can be fixed later.
I like the simplicity of the UI. Once you open the game, most gamers would instantly know that this is a platformer. No tutorial required.
If this game was on mobile and level were not too short (understandable - you only had two weeks to make this, which is still impressive), I would've played this on my way to work several times.
I can see this being an endless runner/platform hybrid with the exception that you can actually run back as well. For a first game, its a very good one.
I'll be interested to know what you'll do with this game like how you'll develop it.
