Fantastic art <3. The music was also pretty nice and chill, fits the game.
Some minor feedback:
- I would still add info about inputs. Only later on I noticed that Space key can also be used.
- This type of game would greatly benefit from having a sort of gallery with all the cards (and not yet seen ones in grey). Much better replayability imo. Also some "New!" text about cards that I did not see yet could increase focus when spamming pack openings (so I won't miss that juicy art).
Minor Bug: Choosing to not open the pack results in the pack being constantly displayed. It can be workarounded by selecting the spot with the machine again and opening a pack so not a blocker or anything
