Thanks for your feedback! I would like to share that cursed cards ARE actually balanced and there ARE consequences for using them, but this could be found out only on the last 4th level...
Spoiler: all the summoned cursed cards will be against you.
Thanks for playing, your feedback and suggestions how to improve the game!
Sorry for any inconvenience because of escape key and popups. There is an opportunity to use left and right keyboard arrows to get back to the previous level or skip it the next one respectively, so if something like that happens it is possible to skip levels which are already completed and return back. I know it is not an ideal solution, but the submission time ended and that's the best one for now.
