Thank you for playing, and thanks so much for the input! I felt the same way when I played too hahaha. These lovely bits of feedback will be very helpful when we polish the game up after the judging/ review period of the jam is over!
We definitely had planned to have levels, as well as other mechanics and behaviors in the boss fights, but ran out of time. If you're at all interested, we can even notify you in the future when we release a more refined version of this game!
