YO THATS FIRE *me wondering what language u used to make that 😯*, and also speaking of collections, I made some pirate themed artwork: ONLY 9 LIMITED OFFER BONUS ART LEF - https://kage11.itch.io/pirate-themed-art-can-be-used-in-games
Not sure if you actually paid attention to what I said, or you're just advertising.
But, I used Construct 3, pretty useful for beginners like me! As for the art you made, I normally prefer to make my own artwork, I like the handrawn feeling I get from them. Plus, I don't really buy stuff in Itch, sorry!
