Connection to Theme: 3/5. I don't think simply retro style completely fits into the theme.
Enjoyment: 5/5. This is my FAVOURITE game on the jam so far, I love it and I'll probably keep playing it even after the jam, especially if you're planning to continue its development (good luck if you do).
Presentation: 4/5. It's awesome visually. Everything follows the general style, attacks look EPIC, units are unique. Though the lack of any background music is a shame :(
Gameplay: 5/5. I can probably play it for hours it's just so replayable. Endless combinations of units to choose from and enemies that force you to think how to change your setup to beat them. Though I wish the player was more involved in the fights, like if there was an ability to command units or at least drag them for short distance in case a buffer randomly rushed into the front line.
Creativity: 4/5. I've seen similar games before but this one is pretty unique in terms of units and buffs.
