Sure, it would be very interesting to create a metrovania game based on these assets. Are you planning to add some bosses and more enemies to this bundle?
Yes, I will do at some point, but focus for the next month is on my 'Pocket' series of top down packs.
In my pack Moonlit Dungeon, it has the same style to this one but has a couple of extra enemies, plus a legacy player character that is fully animated and can be used as a boss. Hope that helps for now!
