Very unique idea. Though I feel like it spirals out of control rather quickly - and given the constant time pressure you're under there really isn't anything you can do to get back on track. That certainly fits the "out of control"-theme, but personally I would have preferred a purely turn-based system that rewards thinking more carefully about the ruleset that guides the spread. Anyhow, for a 48h game jam you did a really good job: love the minimal asthetic, the sounds fit very well, the twist when you're overrun is funny and nicely introduced and it seems you managed the scope of your game really well.

Can confirm I spent too much of the 48 hours trying to balance it, but it was always a super fine line between not being able to lose and losing too quickly! I decided to lean towards the game being a shorter experience since people would be playing many games this week (and I ran out of time for a few aid ideas I wanted, like limited "bombs" that could completely clear a large screen area). Thanks for playing and the feedback!
