I like the base idea of a first person movement game but there are quite a few issues.
It is not clear which enemies are optional and which ones are required to be killed if I want to open the next door.
The movement isn’t explained clearly. The description says shift to dash and ctrl to slide but it doesn’t say you can’t dash on the ground or what exactly slide really entails. It requires a bit of trial and error on the player’s part to understand how they function. Sliding can give a lot of momentum if used correctly which can be fun but it’s properties are not properly explained to the player.
The rapid shot guys are really hard to deal with, I only managed to kill them by pure luck. All the shots going through walls doesn’t help. Some sort of visual/audio queue for when an enemy is about start/stop attacking would be great.
Since killing enemies restores health, you can generally tank a hit from the rapid fire guys when you have 2 health. In my opinion, the game should have either started with 2 health OR there really shouldn’t be a rapid fire guy in the stage where you only have 1 health
When I kill an enemy, their bodies stay solid for a second longer. Meaning I can’t kill groups of closely packed enemies in quick succession without jumping. And when I do jump it’s harder to aim my attacks.
I do think the movement options provided in the game can be really fun. It might have been even better to focus on the movement and make the game about dodging and weaving instead of trying to get into melee range of a Gatling gun to hit it. Simply having no locked doors that require you kill certain enemies would be more fun in my opinion.
I also experienced bugs where, when I die and respawn at the first checkpoint, the guy I killed before reaching this area respawns and shoots me through the wall. Another bug in stage 2 sent me back a checkpoint when I die really close to the locked door.
