This is cool. I played it for longer than i thought I would. Couldn't get to the end though.

Its cool that you randomized the levels too!

One of the best videos i watched recently that has really influenced me is this on below. I mention it because I was reminded of a quote from it. it was something like. 

"If you have a button that does something in your game, you need to give the player a reason not to press it".

I noticed I was holding down the attack button, and because the attack has a long initial attack it becomes a little passive. e.g I'll aim towards the enemy and concentrate on dodging attacks.

Just throwing ideas around:

• maybe you could have a melee attack, and maybe you could parry or re-deflect attacks if you melee attack the projectile.
• slight recoil on the shot might make the movement a little more active, as you would need to reposition.
• Maybe the stationary enemies could do a brief chase for a few seconds, then switch back to shooting. That way they are always pushing you and making you adapt.

Anyway! Great submission!

It's always fun to see a 3D game made for jams, but I think this game suffers from lack of interesting decisions to make. Even something as simple as "here's three powerups you can pick from, choose one" would help a lot.
