Hey! Gameplay was really fun, I liked the variation in weapons/items and enemies. Seems like the levels are somewhat random generated? Kept it fresh after dying.
Some constructive feedback:
-The camera goes too far ground and you can see the background below the floor
-When I die, I really should keep some stuff, like exp gained/ weapons collected or a health boost. That would motivate me to continue playing. I only got to the cave and kept dying because my hp was 10 when I entered, So everytime I died I came back with 10 hp.
-Would be nice with some particle effects. Like dust when enemy or player lands on the floor. Blast effect when a weapon is shot and a simple impact effect when the bullets hit the enemy.
(Vultures are too big etc...)
They looked cool both before and after. I think you should focus and adding more detail to the backgrounds and floor instead of changing details
Also well done with the different AI types.
Awesome death sound effects
Good luck
