Hey Psynut, thank you for taking the time to try our game and for your nice comment!
We're glad you liked it :D
No it was actually not intentional, you unfortunately ran into a bug that we didn't have time to fix before the jam ended :/. We've published a fixed version, the link can be found in the itch.io page. However, the boss is sometimes hard for some people so it ensured that people could actually see the ending even if they didn't manage to pass it x).
Maybe some difficulty management would be good but we had no time for that unfortunately.
Thanks again :)
