This is really cool! Love the idea of having a deck to climb a mountain, losing and replacing cards as you progress. The game has a very nice pace to it and the interactrions feel very smooth.
The art is lovely! I feel like everything is slightly blurry, but I guess I got used to that quickly.
The game could use a tutorial and maybe some visual element of you climbing (maybe a player model?
I really enjoyed this! Well done
