This game is cute! And well-put together, to boot!
It's simple, but it plays well and is easy to understand for what it is. I was impressed by how well differentiated all the wizards were and how none of them felt over or underpowered relative to each other. I was especially worried about the poison wizard who I thought might suffer from unreachable dead zones, but it seems like you thought of that!
Also hey good job on making the slimes a random color every time! They were the cutest!
