Looking good, if a bit simple :)

You probably want to make it a bit shorter, if you want people to stick to the end.

Works without a hitch. It would be interesting to try and make the jump height vary based on how long you hold the jump key.

Gemberkoekje: Thank you! I actually like it long, as it gives a real challenge. (if a bit difficult) ;)

caranha: I think that was my original plan, but I like the constant jump height too.

good and simple. The collection noise is quite annoying to me though.

Simple working game!

Yeah that was weird but I played it to the end.
High score: 93:6

Thanks everyone :)

TheGamingProject: Very nice! :D

Oboy that door opening sound hurts my ears! Cool warmup game though.
