yeah, we had a lot of puzzle ideas but we didn't have the time to finish them, and about the art style and the boss fight, spacemore who made all of it, He is one of the greatest people I have worked to be honest.
and yeah you're right we spend so much time and effort on the boss and platforming, we want to do more puzzle levels but we didn't have the time to make it, but we may continue it in the future if we see many people loved it.
