This was easy to pick up, I ended up coming back several times to beat the game.
Swapping around my team to maximize the bonuses was a interesting mechanic, it adds a lot of depth, at first the monk seems better than the warrior but the warrior defense buff is really powerful
Same thing with the exp->larger team that others mentioned
When units are really close, it can be hard to tell which health bars belong to your guys
I don't know if there is a way to check the stats of deployed units
sometimes I need to unpause in order to drag units around
