This was fun! Unfortunately, a bug in round 28 stopped from going any further. The boss for 28 was stuck in T-pose, and after I failed to stop him the next round never started. I had 4 lives left.
Thanks. I attempted to fix that bug exact bug but ended up cutting it too close to the deadline. My "fix" ended up creating 2 more bugs, 2 minutes before the deadline. It is what it is. After the jam is over, I'll fix all the bugs and add several more features that had to get cut. The floating sign was going to be a bank where you can invest money to get returns after each wave.
