Thanks for playing!
I'm glad you liked the puzzles! I had them in mind before the jam as an incentive to make my inventory system more robust, and I thought it would be a fun unique way of interacting with the world. I do plan on fixing up the inventory system to make swapping items easier, just something I didn't have time to do during the jam.
I've seen the boss either work fine or completely break, and it seems the cause is it gets stuck in a state where it thinks its still attacking but it isn't. I'm assuming it's because it screws up when switching between attack types.
I'm happy to hear you liked the change in style, I wanted to portray a sort of evolution in complexity and difficulty. I don't think I totally nailed it here, so I'm hoping to experiment more with that in the future.
Thanks for all the feedback!
