Thank you so much! We appreciate a lot the feedback. Yeah the music is our own, made by our music composer Chili Max, and he was really inspired by Chrono Trigger for it.
And the third level is the one we are getting the most complains, plus the fact that the more enemies appearing in the level after you die/respawn seem more like a bug than a feature, we are thinking of possibly adding two more levels before that one to teach one specific mechanic at a time, it was mainly a case of not enough time and not enough experience at level design from my part, I made most of the levels except the last one, which was mainly done by another team member and then I handplaced the tiles and edited some platform positions, while also adding the box trapped puzzle.
And how did you solve the third level if I may ask, I am assuming you didn't throw the box?
