Thanks for giving our game a try!
"(...) i just don't make it over Stage 7 on regular basis which seems to be a noob-problem I guess :D"
Any chance you could share a recording of how you play? Our goal is to create a game anybody can play regarding of their skill level so it really helps being able to actually see how others are playing :)
"But at some points it feels like a) I get stuck with the curser in the parts where our character will proceed to the next room (sometimes I also got stuck out of the stage, if that makes sense)"
Did you actually get stuck and had to use the "Unstuck" button in the pause menu? Or was it just temporary and then the game teleported you back into the room?
"(...) when playing in full screen and things get "rough" (level 7 and above), I slip out of the frame, so a locked full screen would be really helpful. For now I assume this is not possible because it's browser based"
Yeah, I don't think we can avoid this within the browser, but I'll verify that to make sure!
Are you on Windows? If so, then you'll be able to play the non-browser version very soon!
