I dig this art style! It’s pretty unique. Sometimes it was hard too see where I was going, which may be due to the very low contrast and brightness, but I liked it overall and it fit your story and writing pretty well.
I actually don’t mind these kind of 2.5D graphics. However, like the other commenter said, placing the character at the center of the camera would’ve felt much better. It also seemed like all interaction prompts appeared depending on whether the actual character sprite was facing the items, instead of them appearing based on the direction of the camera.
Jumping was a bit floaty, but in this particular instance I didn’t mind too much, as platforming wasn’t the main focus of your game. Combat, however, was indeed its focus and it could see much improvement. The only strategy I ever used was getting close to the enemies, slashing, dodging backwards, repeat. More enemy variety, attacks and abilities would have helped a ton.
I liked the sniper boss fight, but it felt like you were forced to make him not shoot the player when he got close (or maybe it was a bug on my end?). Also, the gun could have used a dedicated aiming mode instead of having a “laser” appearing when looking at enemies, but I think you did what you could given the time constraints.
With more polish and combat variety, I could see myself playing a longer version of this!
