The game looks cool I don't at all want to take that away from you and it's obvious you put in effort making this, but dude, you should really learn how to add the extremely basic graphics option to give the player access to fullscreen and windowed modes WITHIN the same build instead of releasing separate builds. It's Unity afterall, the ability to do that is literally already built into the engine.
Oh cool, so even though my thoughts on your release were overall positive, instead of being reasonable regarding the extremely minor criticism I gave regarding a function that is available in virtually all games, which is a pretty universally expected QoL feature and which, again, has a function for it built into Unity which would only require you to add a few additional lines of code and a basic button to enable/disable it, you decide to seethe and sarcasm-post because you need me to Google something for you.
