First!

Link to the download seems to be down. Take a look?

Reuploaded, try now.

Cool idea! I had some trouble figuring out exactly how subspace works though

I collected all four artifacts, but the way forward (NNW of where you get subspace?) is still impassable. :(

The lantern could've had a slightly larger radius, but I found my way around easily enough. It felt like doing pure magic mirror shenanigans in "Link to the Past."

In certain parts of the maze there are areas that are linked via subspace. A good strategy is to occasionally press z and see if you're on some part of subspace you can move in. It should look like the third screenshot.

I got frustrated pretty quickly while browsing the crypt. Also, I didn't really understand the function of the subspace mechanic...

It looks like this didn't quite get finished. It would be nice to have some kind of simple ambient audio. The idea of switching between the two spaces two navigate the maze is pretty awesome. (Took a while for me to find stuff :) ). Although I'm almost positive I got all 4 artifacts, and the wall still didn't let me through :/. Also, when you switch to the subspace after getting an artifact, the artifact reappears.

I wasn't able to find a lantern, pressed X everywhere. Pressing A made it say "you found the lantern" but upon going inside it was still too dark to see.

For anybody having trouble finding the lantern, I added a picture of its location.

I really like the aesthetic the lantern gives. And I think it's a really interesting idea; the "sub space" and being able to walk through walls. Would be great if fleshed out and finished.

I got all 4 artefacts but it didn't acknowledge that I did when I went to the end :/ Apparently I didn't have all 4 artefacts

I like the idea a lot.

Very nice theme using, also hard game.

There are good ideas in this game, I liked playing it, only you should add more challange to it.

I like the concept a lot. Using it with a dungeon crawl or rogue like would rock.

The concept is nice, but it gets too confusing early on. I'd like to be eased into it a bit more.
