really love the vibe of your game! it comes together really nicely and feels like a strong foundation!! one thing I'd recommend is either removing the border around the button choices, or allow them to be selectable as buttons with left click (or right/left arrows as you have now.
I ended up left clicking "Mage" because it "worked" before (really, the option I chose was just the left one!) and then was disappointed to find I was an archer. It makes sense now but just felt a little unintuitive at the time. great work in the timeframe!
