I had a lot of fun with this demo. Definitely spotted a lot of inspirations from other games like Ultrakill, Borderlands, and CP2077. If a mix of those games sounds interesting to you, I recommend you give this demo a shot. Kinda confused by the other reviews because it straight up tells you that you can quick save and quick load (maybe that was only added recently?). I also don't see why you would need to load a specific save since you can replay any level as many times as you want, and the levels themselves are pretty quick, unless you're spending time searching for the hidden items (which you can always come back and do later). My one complaint is that you can't change the difficulty to a higher one after you've started. You can only go lower, which kinda sucks. Hopefully it's not like that in the full game.
