ohh i'm not familiar with rpg maker 2003 so i just really enjoyed how cool of an aesthetic it was haha. either way there's nothing wrong with using default assets, and i still think they made for a super cool presentation! :D
making the game more focused on gameplay i think made it stand out in the jam, but it'd also be really cool if you tried making something more story-based! it's always good to try to hone new skills, ya know?
