1) UI felt very surreal at first glance. Character creation is put on the screen as a small window that is easy to skip if you want to close the main popup at game launch.
2) Movement feels wonky at times where you are trying to shoot enemies but instead walk towards that aimed position. Combine that with the camera that rotates when you move and it can feel quite chaotic.
3) The combat itself felt quite repetitive in the sense that there is no downside play ranged. You have a very safe position and pretty abysmal cooldown between seemingly infinite ammo. The 1, 2, 3 slots felt lackluster in comparison.
4) Infinite spawners feel bad in a way that you dont get a sense of accomplishment. It quickly changes the goal from exploring to speedrunning because staying in one room for too long leaves you more vulnerable than anything.
5) The picking up of items (if that is even possible) is not possible for me. Whether this is due to precise controls needed or some bug, I have reason to believe it led to me not being able to progress through certain areas with a locked door mechanic.
6) If the combat were a bit more skill based (less point and click from safe distance) multiplayer could be quite interesting.
7) For a fun competitive game mode I would suggest a mirrored generated dungeon setup that meets in the middle. This allows for players to gain an edge because of exploration and combat in ever changing terrain.
