Regarding the game's optimization... I'm not able to do much. Shaders in Clickteam are very laggy, and there's nothing I can do about it. If you're lagging, what you could try is making sure you have the latest version of DirectX. You should also make sure all your PC drivers are up-to-date. If nothing changes still, then the last thing you could do is using the shaderless mode.
