It's a nice little game loop, I managed to get all the enemies!
Graphics: -The player model seems a bit weird since it glossy +The enemy's models are great! +I like the way the shadows look and the color theme gives it a nice mood.
Gameplay: +Simplistic yet easy to get your hands on.
-If anything I would have liked to be guided at the start, the bright shining urn was not always easy to find, and well, the first time you don't have enemies, which I'm not sure if it's really necessary.
-The green ghosts are a bit too annoying to deal with, considering the lack of indication you're taking hit (except the health bar) and how two clouds can stack together (with the ticking being really fast), coupled with the fact the orbs are left on the ground.
-Enemies are always clumped together in groups when they spawn, which prevents it from getting too hectic, but at the same time creating a mob of green ghosts that can spawn right next to you at start.
-Upgrades to your enemies, but nothing to get stronger yourself, which is a shame, I think it would have benefited here!
-Lack of sound makes it hard to get a feel for things. Taking damage, firing, killing enemies..
+I love the friendly fire!
Minor complaints: At first the heads dropping to the ground were fun and wonky to deal with, but then I realized it blocked the shots, and the orbs also would get bumped away from shooting them.
The level design could sometimes be a bit weird, putting a wall in front of your spawn directly.
Overall enjoyable! Good work!
