This game is great! You got a lot of things right here. It might be the most fun game I've played so far. I liked that each level was rewarded with a new message, it was enough to make me want to see what the next message would be. One thing I really really liked was how you loaded each level seamlessly as the player is busy reading the messages, that was really well done, it kept the momentum up and gave the world this slight non-euclidean geometry vibe. I was surprised by the amount of mechanics you introduced too! I like that the level design varied quite a bit, some were more vertical etc. There were some buggy enemies but it wasn't too major, some were invisible but I could see their health bar and still shoot them. The mouse sensitivity was quite low, thankfully my mouse can increase the sensitivity.. otherwise, I think the game would've been quite hard to play and less enjoyable. I appreciate that the upgrades actually felt significant and it was always a nice reward after beating a level to get some kind of improvement and yeah, actually notice the difference in the next level, not a major difference, but still a difference. Really great work! :)
