A simple but very effective and addictive concept! Buying buffs and debuffs at the end of each turn is really cool, and the whole system works well! And the 5-second timer is actually really well-balanced—it’s neither too long nor too short!
Also, it might be nice if the AI took a little more risk or was a bit more aggressive, since it’s maybe just a tiny bit too easy right now, but other than that, it’s excellent!
