I really enjoyed this demo. The aesthetic stands out for me because it is familiar to a Metroid lover, but also feels famliar to a human who lives on Earth. It's a delightful balance and I am eager to see what else you come up with.
If I may ask, what program/s are you using to make this and how hellishly difficult is it to learn to produce a playable game with it/them, art design aside?
Thank you for the work you've already put into this project and I hope it exceeds your expectations in every way.
