Original concept, and great implementation of dual perspective! I liked the concept of protecting your plants, sort of like a reverse TowerDefence.
The game guides you through thoroughly, but I feel like the first night might have taken too long to come. I kept checking to see if the enemies were going to spawn, before the capsule mobs finally appeared. The combat feels like it could be fleshed out more, with visual feedback of attacks landing or damage taken by player.
This would be a good base for a polished game to be built on.
