Hey, thanks for picking up the bundle! I looked into getting you a refund and it looks like the only way is to contact support. As per itch's terms of service "To request a refund, please contact support with your purchase information". So, send them a quick message and they should process it. If they don't give you the refund for any reason, send me a message and we'll figure out a plan B.
Enjoy Hardlight Station and the rest of my games!
