Thanks for the feedback!
We had more planned, but after some pretty major setbacks mostly towards the end, things got scaled back and reworked a bit.
It was our first jam as a team, and my first jam in general, so it was a learning exercise for us to make things click. I was doing code and audio, my teammate was doing 3d art and design.
A note on the second boss, the main strategy is to destroy the beating heart in the middle. The boss himself doesn't take much damage.
The shadow is a good shout!
