A fun take on an idle game with a survival twist! I was panicking smashing enemies with my hand for a while at the start that I didn't realize I could purchase the upgrades. Good thing I realized because that made life a lot easier.
I thought it was cool that structures were added over time, but after a while, they became more of a nuisance than anything since they blocked the view of the monsters. Maybe giving them collision would help or letting the player purchase and place the buildings themself to unlock new things? Just an idea!
Very cool concept.
