Sorry about that! I did not make it super clear but if you hover over a gold circle where a save button is on the map, you can teleport to it! Thanks for your comment!
Good job on making it so far! I didn't expect a lot of people to stick around so long in the game! Yes, the difficulty curve of this game is very high unfortunately as you might have seen the really early boss fight. I can try to improve this section of the game. Thanks for your feedback!
