Thanks for the feedback. I have to admit the controls are not the best part of the game (but maybe should be, considdering a lot of it is a platformer).
In Level 3 there is hidden (second) finish point below the bridge. In that level you don't die from falling in the red pit. After 100 seconds you will get a hint in some levels that helps you finish the level. But i understand that the level design can get frustrating. Very valueable feedback for me.
