It's probably a great game, I can't be sure because I'm not much of an FPS player, but again... idk if we can call this a FPS game because it's feels more like fighting one.

I'm actually having a skill issues with the control because, I have to constantly moving while holding LMB while directing the camera and pressing dash with my pinky finger which timing is always off because I never used my pinky finger to play games, so yeah it's just probably me who suck.

I also tried to jump by using my thumb on space key but it's ruined my hand balance so I kind loss some pressing power on my Mid, Index, and Ring finger whenever I jump so it's feel like I didn't moving much when jumping and still getting shot by the boss, again it's just probably me because I usually only use three fingers on each hand when playing games.

After a few tries I managed to defeat the first boss (not the unmoving tutorial one) because both of boss and player does a range attack so I can call it a fair fight but a second boss are really not my cup of tea.

The second boss seems come from a fighting game or something and you know the results, the second boss always target lock me + it's movement speed are seems to be faster than the player to the point I can't outrun it even after spamming dash as if the boss can teleport, I stand no chance so I give up.

*Just a suggestion, I think you should make your camera view point similar to something like Resident Evil 4 to minimize the blindsides, I found it hard to evade the second boss because that thing constantly enter my blindsides, if your game is just about shooting each other then normal first person view are fine because you can see the incoming attack from the front but I don't think that's the case if the boss suddenly goes melee and expecting player to constantly swing their mouse around nonstop to lock on boss which constantly charging at them doesn't sound right.

That's all I guess, if I write something wrong or missed something, let me know.
