I found this really fun to play, but it is in need of a few updates. The gun aiming could be smoother, as with looking down the sights, instead of just teloprting your eyes to the guns sights.
1. Add a presentable menu
2. Change the resolution so that it is more playable
3. Add a mouse lock so it is playable
4. Have you even played MineCraft? It's nothink like this.
5. Finish your game before uploading it, or atleast in a state that would be fun to play.
Games like that are too commenly made, but know they have better graphics, physics and are more unique. Theres no space for theise games anymore. It would of been god 5 years ago
