Thank you for the feedback!
I think the scroll wheel would have been better for the character switcher but that would have required a lot more work so decided to put it off until after the jam. People have mentioned the buttons before too. I didn't think it was that big of a deal but apparently I was wrong. I do like the idea of being able to click the characters. I'll need to rewrite the switcher script because a lot of people recommended I fix that.
I'm glad you enjoyed the game!
