I've encountered some bugs with the game that make it rather difficult to play and I think you can really improve as a game developer if you give more modern game engines a try, because a lot of problems with this game stem from Clickteam Fusion 2.5 inner workings (like fullscreen mode not working and built-in platformer movement being extremely buggy).
Nonetheless, the ability to edit game environment in real time by drag-and-dropping objects is not an idea you see in games very often and it definitely has a lot of potential that you can work with!
Thank you for submitting your game to the Ms Paint's Jam!
