An interesting concept, a little simple execution wise, though it is a jam game. It was interesting to figure out some of the timing on the NPCs, though it was relatively simple to just run towards the town hall. Except for not knowing how long till the sniper would hit you of course. That made it a little harder.
The only real critique I'd say besides the difficulty is the visuals don't mesh the best, which to be fair for 3 hours makes sense, since you were focusing on mechanics. But I figured I would point it out nonetheless.
Though the audio does fit relatively well which is nice, I couldn't tell if it was changing depending on the situation, or if I just had incredible timing.
