Thanks. I'm glad you enjoyed the game.
Yeah, the whole project was a bit of a struggle to put together that quickly. Part of me wants to re-visit the game and build a new, enhanced version of it from scratch at some point.
After a year of learning how to code properly and make "video games" I still find level design to be perhaps the most difficult aspect of the entire process. The YouTube channel you suggested seems to have plenty of neat videos concerning game development overall. Think I'll take a look.
