Sorry we didn't catch up your comment sooner. We're adding a new build around April 21st (with more decks/levels) and will add a downloadable version for Windows and Mac then. We'll reply to your comment again so you can get notified ;)
Hello @Osiride ! The game has been updated, and loading issues should be fixed. If you ever have any trouble with the web version, feel free to download and play the desktop version. Have fun! :)
