Fun idea, great music and sfx fitting really nice. (Well, if you consider the title, we might think if it fits ;) )
UI is simple, yet effective. I don't think there is any info about how many fruits you need to get to build a soldier?
I also disagree a little about the choices you made regarding steering - the WSAD and shooting is obvious, but I'm not sure about the rest - the change between actions feels a little strange to my. Id personally remove the pickup as action, and try to pickup automatically on entering, as it works with delivery of the fruit. But I think I get the idea why it is done like this :)
I think the game needs a little more tuning, but I know from personal experience with this Jam, its something that's not easy to do in a given timeframe. I mean - at first I thought - hey, the soldiers are OP! Than I realised I can fire like a machine gun and I oneshot everything (should it be like that?) while being indestructible ;)
