This is a good platformer. I quite enjoyed the mechanics and I think they were well made, even if I encountered few bugs like using the dodge and getting stuck inside a wall and after dodging onto a red-platform I didn't die from it (until I jumped). But overall I think it has nice potential, the flare system is really fun too, kinda making your own light along the way. I don't know if you planned the flares to be limited but I quite liked throwing them around so I'd rather them not be limited lol. But anyways, shooting was nice too, right now I think it only lacks the impact. Platforming is simple yet solid, the level design quite highlighted what you can do with the platforming, like using the huge drop with bouncing pad in multiple ways. Lack of time is always understandable, and I assume the lack of time is the reason why there is no UI for health or sound effects for the pickups and more cohered tutorial for the movement mechanics. To be fair though, aside from the dark ambient mood, there was not much "horror" right now.
Good work nonetheless, and I recommend continuing development further ^^ Lot of things were fun right now already.
