You have real skill (and enjoyment, that’s clear) for making up silly little guys. I’m glad you let yourself be indulgent on this one, it was a lot simple fun, even without your signature novel rulesets and punishing difficulty.
This is an idea I’d love to see you revisit, if you are ever feeling it! Having this kind of concept combined with your mechanical style would be so interesting.
If you like the GBA era of Fire Emblem, check out the “Storge” romhack (if you haven’t already). It plays with the exact space you outlined here!
