What an amazing concept, so simple, so easy to immediately pick it up and keep playing for awhile. I like the upgrade system to make it like a survivors style. I'd def say I wish I could better visualize enemy movement, the little image that shows when you hover is good, but it can sometimes be hard to tell just how many squares they can move, perhaps highlighting the actual ground of danger squares when you hover the enemy would be a good QOL change? Overall this was an awesome submission!
