This is very impressive, given the time constraints! I’ve ready your devlog, and as a fellow Love2d first timer as well, I totally agree with your feeling: it absolutely gets out of the way, allowing you to build whatever you want on top of it.
Is this game open source anywhere? I’d love to see how you managed to handle your animations, especially the “trail” on the last boss’ moves, it was very very well done!
Also, great job on the screen shake and the little details like the red squares moving inside the HP bar.
Definitely one of the best games I’ve tried in this jam!
