Nicely polished; it works, it looks good. Good job.
I could only play with the bot so I'm not sure about the strategy, but it's a very interesting take on the theme! I wish I could play with someone to see how it would "feel" in the real world.
You could still do both tactics against the bot and earn the achivements, but yes playing against another player is more fun. Online play seemed overkill for this short jam and would have caused much less time for polishing
