Fun game and good job including multiple wildcards. It took me a while to get the hang of it, but I guess that is to be expected for the "game with no tutorial".
The Simple Shapes wildcard really made a big difference in the design for this game, which was certainly unexpected for me. I definitely understand how it's confusing especially with the current upgrades system, so hopefully I'll be able to look into a more intuitive system in the future.
