I found success, but the game seems a bit trivial once you figure out what's going on. Being able to hide the heart in an unassailable fortress of eyes is kinda unfair, but since enemies only spawn when you choose them to and only if you put some in your deck, finishing is kinda simple. It seems from the comments other people have taken to minimizing the number of played cards as an unofficial hard mode, but that seems kinda overly luck-dependent for me. Nevertheless, the game was fun, and it feels sufficiently fleshed out imo. Thanks for making this!
