Thank you for your feedback! Yes Zinky is a bit slow,it was kind of a design choice at the time, but I agree we need to make things a little bit faster, including the gravity. We plan on adding new levels,as well as différents backgrounds (different levels within different "worlds"). For the ennemies, that's a good idea, we need to think about how Zinky will interact/inflict damage to them. Thank you so much for taking the time to provide this detailed feedback. We'll upload updates here on itch soon.
