While clearly reads as someones first game, its a complete game in that it has a ending, and knowing its all made by a human made me enjoy all of its rougness in a strange way haha. I think I liked the music most because I also had tried to make some retro music a while ago and I think it sounds similar to my attempts.
I couldn't finish the game though, died so many times on flamey level (lv 3 I think) that it started feeling like a rage game so I gave up lol.
