Reminded me a lot about shenanigans in UT99 classic with portable teleport.
Few issues:
1. It is really hard to read the level visually, especially depth. I think combination of visual style + lack of shadows might be doing the trick. I see you've added FOV slider as a possible mitigation (probably) but it does not help at all.
2. Consequently, this make it hard to read and gauge the lance throw + lance itself it not really good an indicating its path. May be consider gizmo-line helper?
3. Battles are boring, it felt like they are here just to be here. The whole, pull level, fight a wave gonna get tiresome real hard. I rather see fewer enemies but hard to catch then bunch of dolls to chase.
4. Jump is a bit too floaty, might wanna experiment more with it.
