This is a really cool combination of genres, I love tower defense and farming games so this is great. Good job on the art too I like the machine gun scarecrow's sprite. This game is super fun I enjoyed experimenting with strategies for which scarecrow to use and which plants to grow. I tried a good number of runs and I wasn't ever really able to get my farm to pop off like I wanted it to. At some point a really crazy amount of crows come and I never had enough scarecrows to defend my crops. Idk if I'm just bad, but it'd be nice if the big crow packs came later so I could build up the farm a bit more. I think it's kinda hard to tell when crops are done too, the finished sprite is only slightly different than the almost finished crop sprite and it sucks when you harvest a crop too early and get no money for it.
Overall tho this game is awesome, I had a fun time playing it!
