Cool game, y'all. Sounds like you had a huge team. Congrats on being coordinated to pull it off and push out a game in a week. Well done!
So I think I had a bug in my first run. After like the second wave, my bullets all shot at like a 45 degree angle downward and I couldn't hit anything. I made it further in my second run, but I kept getting hit (and ended up dying) to enemies spawning directly on me or behind me. That felt pretty bad.
I really like the enemy sprites. They're all goofy and wonderful. And the 2d sprites on the 3d looks nice and has a bit of a retro feel to it. The music was a good fit.
Overall, y'all did a great job. It's got tight controls and feels pretty good for a generic shooter type.
