This was a fun game and I had a great time playing, and It reminds me a bit of King's Pyramid (a solitaire variation). I felt the difficulty was inconsistent... Wave one had me combining multiple cards to make matches, and later waves didn't have me combining any at all. It was also annoying to have to refresh the page every time I wanted to try again. I thought I could alleviate that by exiting the game before I lost, but that cause a glitch to happen where I could win the game with one play, but I enjoy that tbh. I also didn't have a lot of opportunity to loop the card values.
