Thank you for your comments.
The enemy appareance should be fixed as soon as the jam is over, about the controls, are made intentionally: you get more control over the character movements with each level you advance.
About the collection, i will polish it too to ask for more points to evolve which every level, perhaps asking for 10 more each level.
I think i surpased the average skill needed because those tons of test i made to refine the system, but i'll consider all your observations.
Thank you for playing and for taking the time to give me your kind feedback.
