Hey!
It's been quite fun. I wanted to play this game since MVM 22 but didn't have the time. Nothing bad to say at the moment, the game is quite charming and feels very well polished, also very cute. As mentioned below; I'd like the cooldown to be shorter for more agility, although it's not bothersome.
I played for a good while until I ran into a bug when falling on a spike. Something to do with obj_transition.first.
Other than that, just wanted to say I loved it. Well done!
