interesting game concept, the controls.. hmm...well, they need time to get used to. when spamming the shift key to jump, there even opens the accessability-popup from windows offering its assistance ;-)
Once i got used to it, it worked pretty well.
In case that yo plan to extend the game, it would be nice to have more different rooms/tasks. going left to right and back again gets a bit repetitive.
Overall a good game concept!
