Definitely one of my favorite new games an am eager to see it grow into a fully realised game. I love how the 50/50s can be worked around with the artifacts and the number swapping curses are brutally fun! My favorite relic is definitely the counting lens as it opens up a whole new avenue of thinking.
I was able to get this absurd run where i could re-roll level rewards 6+ times and choose 14 different items. probably totaled 200 re-rolls.

my one suggestion is that there is an endless mode after the end (eventually where minesweeper just gets impossible in vanilla) that is the true test of a certain build, similar to the games' inspiration: Balatro.
a couple bugs I found in 0.5.6: (sorry i got no screenshots)
- when choosing level rewards with multiple rare candies, the game tries to add more after the skip button, easiest way to recreate this is with 2 rare candies for legendary relic level rewards. issue would solve itself as more relics get added but maybe there should be a limit on stackable relics such as the candy and the guiding flame.
- some boss curses assume the game is in "do not count exploded mines" mode. example: when a bomb is destroyed in a 3x3 explosion, that bomb is no longer visible to surrounding blocks. i also think that exploded bombs should be more visible and look more like flags
- this is speculation but i don't think the pure and soft blessings work as intended. The only curse nerf i encountered was 5x5 vision instead of 3x3. i like the idea of specific nerfs for each curse and each blessing though.
overall this game is so fun! can't wait to see where its heading. keep up the good work!
