Very cute and polished aestetic, especially for a 7 day affair. Gameplay is fine, not much originality, basic tower defence. The difficulty curve could probably be increased a bit, it didn't take long for me to have good enough defenses that I could just tab out. A speed up button would've been a great feature to help this as well. If it wasn't already done, for next time I suggest getting some playtest done much earlier during production, no matter how basic the game is. Lack of combat SFX does also make combat a bit dull.
Neat little game, good job guys, you have a lot of potential!
