Thank you! All valuable criticisms. I actually did have animations on the shop buttons that popped them out as you hovered over them and they stayed popped out when you selected them, but it broke while I was adjusting to get the WebGL build working. And I ran out of time for SFX which would have helped.
I also planned on more complex interactions between the buildings in each dimension, but I wasted too much time procrastinating throughout the week.. My original idea was to have buildings in one dimension produce resources only in the other dimension. e.g. A tree grown in the light dimension, produces fruit in the dark dimension. But it was getting too complex overall and I had to reduce the scope of the game.
But thank you for taking the time to play and provide great feedback! I really appreciate it and I'm glad you enjoyed the game.
