Some things to consider as you move forward:
- In the first level, the goal is behind the gray pillar, which makes it impossible to see; for a while I didn't even know what I was supposed to be doing. Something to change the camera angle would help.
- The difference between a card being active and not active is very subtle, to the point that I rearranged the cards, clicked "go", and couldn't figure out why nothing was happening.
- When I did something wrong on the first level, I couldn't find a way to reset.
