Thank you! I’m glad you thought so - I’m happy with how the art and music turned out. As for game “engine” - I have a simple rendering library in Rust (it’s here, I don’t……. honestly recommend it to anyone but me: https://github.com/mistodon/jambrush ).
Sorry you got stuck there - the dialogue before the fight gives some hints. For that first fight, you have to have Dylan use Stoic to survive the hit.
