Really cool entry! I'm super impressed with how the game looks, as well as the auditory ambiance playing the whole time which really adds to the experience. All of the different features and mechanics in this game that you were able to fit within the month of the jam is really impressive. I think the game could benefit from a bit more of a progression curve, since the enemy waves at night are always the same, but other than that this is a really good game. I'm especially fascinated with the dynamic grid system you were able to implement for the farming.
Also, this is semi-unrelated, but ignore the guy who left a snarky comment on the game page. Going through his profile, he leaves nasty comments like that on almost all of the games he plays, and he hasn't even published a game himself, so he doesn't know what he's talking about. Just ignore him. I know that pouring hours into a jam project like this, especially a month long one, and then getting a bad comment like that can be very demoralizing, so I feel bad.
