I really like the visuals of the game, they really give me the old school 90s vibe.
I do think the arenas you fight in are a little too cramped for what is seeming to be a fast pace first person shooter. (Almost Doom Like). Character Movement/ Controls could be worked on a bit. I felt like pressing E to pull myself to the hook was a bit weird where I thought it worked where it would start pulling me whenever I was in the air. I also didnt really understand what the crystals were for
Aside from that, the addition of a lever editor is really awesome. I also love the enemy designs, especially the snail.
