This is a really cool game! I love it when you have to make calculated sacrifices in a game, and the different card abilities really maximized that aspect of your game. I always found myself making meaningful decisions while playing which makes it so easy to get immersed in a game when it has you really thinking like that.
I did end up getting one very minor bug in one of the levels though where the player straight up walked through a pathway they weren't supposed to walk through. I really wish I screenshotted in time, but for whatever the reason the player kept walking downwards despite the path they were taking having a tile point only to the left. Can't say I'm entirely sure what caused this but I don't think it's anything you should worry too much about cuz the bug never replicated itself afterwards
