I love the game, play Frostmancer with all negative charms as well, and your comment is perfect!! Good job ♥️
About the overall balancing of cards, some should remain better than others, that's part of the fun. But yeah, same as you, Meditate, Teleportation are simply useless with 'hesitation', some like bishop are never picked, because too limited in their use.
Other examples: I always get rid of Jolt cards when I have Dash ones, same for Jump and Knight. They're simply the same cards, but better. Jolt and Jump should have a little extra to make them interesting.
About the rewind mechanic, it's vital in the fun of the game. Players don't enjoy being stuck at the end of a good run with good cards, it's frustrating. And I noticed we can use the free rewind indefinitely by closing and re-opening the game, which I do often because sometimes I like to test a sequence of several actions, not just one, and I don't think it breaks the game. Maybe it would be more appropriate to have a limited amount of 'save points' for each level, that would allow testing several cards in a row.
I never use 'rewind to previous turn', and only used 'rewind beginning of level' once, for a boss.
Thank you again for this cool game! If you find time to keep working on it, will definitely be there to see the updates! ✌🏾😎
