Does it fit with the theme yes. But does fitting with the theme make it better no. It doesn't bring a new side to the normal boss fight. I mean its not bad but its just a boss fight.

I agree, this was my first jam with someone else. It was their first jam, and we had some difficulties in development that caused us not togget done what we had wanted so the end product is a bit more lackluster. The original idea had a large palette of attacks and each attempt would greatly vary up the boss's moveset so that each fight was unique, but we didn't have time. The original idea was more to have a game where you have to learn the tells of the boss's attacks in one playthrough, because if you died the moveset, animations, and level layout, and more would be different, so it was going to be more of a Only One Life. We didn't have enough time to do that and so it ended up being "only one fight" unfortunately.
