Love the ideas of mixing 2D in 3D environment. Some improvement I think:
- Need some kind of indicator on the screen to let player know where the enemies is coming from when they're getting close. At some point I got hit by range enemy that I dont know that they spawn behind me.
- I think this is survival genre right ? Maybe we need some landmark in the environment so that player dont feel lost when running around
Overall this is good, there is room to improve ! Kudos!
