I really liked the creature designs / artwork, and the overall pacing felt pretty good (up until everything got erased; at that point I gave up.) The random egg spawns and trades felt interesting. I had some troubles actually getting some of the cards/critters to go onto the board, especially into the spaces close to your hand of cards. Also I was concerned about filling up all the spaces before I realized you could take creatures back into your hand and you got board expansions for filling everything. How exactly the upgraded ones spawn I wasn't clear on either but I believe it's when you have a triple and expand the board. Overall I liked what I've seen so far other than the most unfortunate loss of all progress. I didn't even think to snap a screenshot, RIP shiny blue legendary deer.
One small QoL request; I really do appreciate when games allow click-and-hold for repeatedly clicking on things (like hatching the eggs). Old repetitive strain injuries are not much fun.
