I died once at the beginning because I couldn't figure out how to use potion (E) and thought maybe it would auto-pot. So now I'm a ghost trapped forever :cry:
Snake game is on the top left corner of the high score screen (below word THIS). Just move your arrow keys and you'll see it. If you don't see a circle to eat, it might be at the top edge.
To get the easy badge, scroll right and left, and clicking letters for 60 seconds trying to figure it out yourself. Or read the instructions and press space to get it in 10 seconds.
I enjoyed the game in general, and moreso once I figured out what I was supposed to be looking for with the puzzles. I'm not going to lie, it took me a really long time to figure out how to solve the puzzles without the QR codes. I went to the comments to discover that the clues were on the floor... in a much further room. I'd consider making the first clue a bit more obvious, like in the same room as the puzzle. Then later, introduce a statue or sign that says "the answer may not be in the room" (or something slightly more cryptic like "the answer falls outside these walls").
I just started. Glad I read the comments because I was about to give up. It was really slow, but definitely is getting better with progression. Looking forward to the rest.
