That is a good jam game in my opinion. I just wished some little things would happen if you just killed humans without collecting them or stuff like that.
The game is definitly funny and it is well polished in everything, menus, gameplay, sound, integration. There is a lot of assets in this game for such a small team with so little time. So i'm impressed by that.
Anyway i'd say maybe for the game to be better, just a litte bit more of user feedback. Having a time for instense or understanding when the game is done in order to try to beat the highscore would make the game more clear and fun to replay.
It's a bit short but I rather a short game well made than a long one unpolished.
Thanks for that entry !
