Mediocre.
If I'm not correct, you're the guy who ripped on Moovlin PC... and you've ripped on issues which ironically you don't see a problem with in your own game.
Now, I know this is already getting fairly poor feedback but bare with me, this game isn't in any means bad, it's just the height of mediocrity.
Artwork is pretty simplistic and mostly static, there is not much to see here, locales don't change often, and everything is clearly made with the line tool. Artwork in my opinion usually doesn't matter as long as the game is functional and fun, proven time and time again by games like Minecraft, Fancy Pants, etc.
But even if this game did have nice art, I would probably only give it a 5.
The gameplay is extremely stale and counter intuitive. The jumping button is mapped to X which is really annoying since the intuitive option would be Up, but since that's aiming, the second option would be spacebar, and that's used to pause. So many time I would pause the game instead of jumping. The intuitive option for pausing would be mapping to P, as that is most commonly used.
Second, when you pause, the animations for your character still operate, which just looks sloppy. The game also feels like a clone copy of this other, even shittier game called Prometheus... it feels like a carbon clone with a female protagonist. The controls work smoothly but the enemy designs are few and far between, and I often found myself stuck in corners having to sacrifice health just to escape from a monster.
Despite all that, there is only one other thing that bugged me, you decided to have voices on top of music, which made it really hard to hear.
Anyways, nice effort, there are a ton of great constructive reviews on this already and if you fix a few of the flaws I mentioned on top of others mentioned, this could be really good. Don't listen to dickless shits who just blam it for the sake of blamming without offering any criticism, first hand experience here, it can be really annoying. With the right amount of effort and dedication put into this, this could be a top tier game
