First of all, let me say this - this is the exact aesthetic I LOVE in games. So, I found that incredibly pleasing. The game was actually a lot, a lot of fun. But I did get very, very frustrated while trying to get past one bit. The part with the lazers (I think that's what they were) and the disappearing and reappearing boxes. I found that really difficult for some reason. And also the fact that all the health items were in the same spot, at the beginning, when I clearly did not need them, and they never re-spawned. Overall, this was a really solid demo, even if I got pretty frustrated, and I can't wait for the full game!

Here's a video I made :)
