I ended up playing this game for way longer than I probably should have. Entertaining gameplay, however the beating it seems like it would take an eternity (unless im missing something). Really fun game great job!
For beating the game, you get the "Toni" Unit at the 800 hunger milestone. Toni deals 100x damage to the fence, and the high hp at the end was to prevent people from only playing with max 2-3 units.
