Thank you!!!
You're right about the tutorial. We had originally planned to give the player a new unit at the start of each stage that they could place and the stage wouldn't start until they had placed their new unit and could see what it does. We just ran out of time. I also had the idea of doing some fly-in tips at the beginning of each round but ran out of time for that too. That's the nature of the beast I guess lol.
Thanks again for playing!
