Great game with lovely pixel work!
You should enable the abilty to press two buttons at the same time, it's frustrating not being able to run and jump. I use Stencly myself and see a ton of these clone games come out because all the sprites and sound effects are available on forge, it's OK to be inspired by other games but ripping off sprites and sound effects from other games mean you have no chance of taking it any further and it also cheapens the whole experience.
Well done on your first game though, at least you have managed to put something half decent together :-)
You should really make your own sprites and why the Microsoft logo?
i didn't find the game particularly hard I just gave up out of bordem.
Advise - Create your own graphics and create some more interesting challenges, dont rush making your game either.
