Hi thank you for your comment! We made the game design and then got inspired by loop hero, but decided to try and keep our own voice.
The reason you cannot draw more cards is that the deck is empty, the number is not showing because of a bug, I'll fix it during the day. And yeah, the storm doesn't come, you play before and there is no time limit. Originally we wanted the storm to come and do constant damage to every monster, making the same loop, now that you have your full deck, but we just didn't have the time to do it.
The paths changing follows a minesweeper logic, leaving only the border, there might be some bugs, it was a far harder problem than I anticipated.
Thanks again for playing our game and for leaving a comment!
