I completed the game (in normal mode).
This was super fun, I liked everything about the game. I love the comic style2D part of the visuals and the view is good and the environment and enemies look good enough. The sound effects work pretty well. The game plays smooth and controls well, movement feels good and the inventory and combat control are perfect. Not only the Void part is a good implementation of the Cosmic horror theme, it's also super fun to deal with, especially as you reach the last levels and staying inside it will get you harassed by eyes monsters so you don't want to (but also want to of course). I really liked that the exit was just behind me, that was great at all and also a great conclusion to a narrative based on an endless cycle. Combat is plenty based on resource management and especially limited use weapons including some dealing with multiple enemies at once if they're here which is quite fun.
I briefly tried Challenge mode because the game is so fun, died on cycle 1005 (I think you then restart from the first level but with all your items or something like that, I'm not even certain and am just mentioning it in case it's true and you're not aware, it does not really matter).
Sometimes I want to enter the Void mode but open the menu instead, not sure what I'm exactly doing wrong. Also enemies can occasionally end up on the same time as the player. These are very minor laments, the game is quite polished overall.
This is an excellent entry, thanks for sharing.
