Thanks for the feedback!
Vezy did a great job animating, and I helped implement the animations into the gameplay. Like you said, some other enemies and some upgrades would've spiced up the content, but we ran into some problems with our other enemy type and ended up having to scrap it last minute. If we had a little more time the game would've been in much better shape.
We had good ideas, but unfortunately we lacked the ability to implement them in a timely manner 😭
