Thanks bigsofty.
the last thing I have added are bumper walls, which repell the player and are animated while doing so. ( Imagine the casino levels in the sonic games

)
I also added air vents, which push the player upwards, based on their strength.
(Nice for rooftop levels

)
I came across many bugs, which where really hard to find ( like wrong terrain drawing when the terrain is hidden and under water at the same time ( I had mixed up x and y variables for the xmovement command

).
Some enemy models have been replaced and the procedure that handles if the player jumped on an enemy or is hit by him has been improved in favor of the player.
Also the editor has more functions now.
I also tried a Linux compile, but the game crashed a pc of my friend ( running Linux mint ). Is Linux cross compile stable right now?
If anyone is interested in testing, just write me a PM, the game is much more user friendly now ( I hope

).
