As usual an ambitious game! The problem- it's a bit difficult for me. I defeated the first wave, and a couple of guys form the second on my best run. The other villages were useful as bait, but they all died too fast :( That's a pity, because coming behind bandits to attack them from the back was pretty fun! Combat was cool- especially when I managed to hit multiple bandits with a single attack.
I guess, like the theme says, I couldn't save them all.
I think you overscoped. For example- you didn't need a huge terrain, if the only action takes place in the village. My usual workflow for game jams is planning the development for half the days available and leaving the rest for bugfixing and polishing. It's sorta what you did in "Limited space in space". By cutting additional game modes you kept focus on the main one.
So yeah, that's my advice I guess :)
