Hello, we're glad to hear you like the game and sorry about the bugs! You can report the bugs by:
Sending a message in the bug report channel on Discord
Making a topic about it in the Steam forums for the game (we're not entirely sure if you can make posts without having a Steam copy of the game, though)
Sending an email to our support email: swordlake.ent.help@gmail.com
Edit: Actually forgot that there are specific bug report topics here on Itch as well!
We will try to sort the bugs out as soon as possible!
