Thanks you for your feedback. I already moved to BlitzMax NG after I saw that it's still in active development on github. It helped a little but from what I see, code of my game is so messy that I would have to rewrite whole game to make it a little bit better. When it comes to fullscreen and mouse control support I can easily add mouse control but fullscreen would be a little bit tricky because of way I programmed my game back at the beginning of my programming adventure.
