I think the demo might have been stronger if you just went straight to the battle screen instead of waiting for random encounters to show up - the battle screen definitely feels a lot more polished. I love the battle music/effects, and the mechanics remind me a lot of the Mario RPGs, which is really cool.
Here are some suggestions for battles, if you keep working on the game:
- something showing the difference between the two skills each character has
- damage text showing how much damage you deal/take; for a few turns in the first battle I did I wasn't sure if it was doing anything.
- "hit" sound effects for when you deal/take damage
Sorry if this comes off as nitpicky - I actually had a lot of fun with the demo, and I think even what's submitted here is impressive on its own.
