I had a lot of fun!
I think instead of having 100 different types of cards it should be 1 card for each image. Then your merges could be more intuitive. I found the merge mechanic to be extremely counter intuitive because there were so many similarly named objects!
Also, a quick intro to the controls would be nice, going in depth of how to discard, play, merge, etc. It took me 10 minutes to know exactly what each thing meant.
I also never understood upgrades or hand types, because there were so many unique objects.
Overall, a very fun and cute game, which I think if scope were reduced to less unique cards it could snowball more like you wanted it to - like Balatro!
Well done.
