The characters seem fantasy but the walls and floor seem futuristic. Sounds effects are attack would make them more satisfying. Haven't seen much made in DragonRuby. Might need to check it out.
Good catch :) I was planning on using a robot, cyborg, or alien for the monsters but had trouble finding artwork that I liked. Thank you for playing! Edit: The DragonRuby discord is very active and welcoming, probably worth checking out.
