Thank you for checking out my game! My goal was to create to a complete experience with a nice little story and I am really glad you liked it. :)
Yes, unfortunately Unreal is a bit hardware-demanding, so I am sorry performance was not that great for you. There are ways to improve that, but Unreal performance optimization is an art for itself and that was a bit out-of-scope for the jam, haha. Still, I am happy could check it out as it is. I will certainly continue with this code-base and with what I learned during the jam. :D
