Hello. Your quest has been a lot of fun. I don't normally do beta testing (this is actually my first one), so my feedback may be a little rough.
Some ideas...
First the leveling. I understand how it works, but could you possibly allocate the skill points instead? It makes it hard for someone who plays with a balanced approach, especially since to spam magic skills, you need to use magic (this could be a challenge factor. Lana is a sorceress after all, so playing thru with mostly magic makes sense to a degree). It also seems that you need to level a particular attribute five times or more, to even notice a change to begin with (at least it was for power). I'm also unsure of what contributes to leveling Vigor and Luck. I assume Vigor is HP recovery and maybe defense. Luck...is it money drop rate? I can't think of anything else.
The save tile everyone has mentioned, still seems buggy. Not sure if it can be fixed, but it seems to not work when you're standing exactly on the tile. if your're slightly off in position, then it works fine.
Stratum 4...I love it. Very nostalgic. But did you seriously intend it to be so easy? For a late level in the game, I had the easiest and quickest time here than anywhere else. Its golden for grinding too. Also, I'm not sure of the point of the Magical Key. This one dungeon in particular has had only one door, and looking at the rest of them, the Magical Key could potentially be game breaking.
Bombs and arrows, almost feel unnecessary. There is only one chest blocked with a bombable rock, unless there are secret caves I can't find. No puzzles, or Gohmas that require the use of arrows. Its like they were just thrown in to be there. Could you add some practical uses for them? Or are they merely optional. This is a bit extreme for a play style, since they can only be bought, there is only one shop, and money is rare to come by in the first place. The Ocarina seems almost pointless too. Only one Diddogger, no secrets, and no wind warps. The Ocarina might do good as a permanent alternative to using the consumable Warp Wire once you've found it.
This last one is minor. I'm having trouble with the image hosting though, so I can submit a screenshot. In the side scrolling area to the flippers, fourth screen, there are three tiles in between the first two ladders that should be walls, but instead, you can walk on/thru them. They're shaped differently too. I found this one by accident.
That should be it. Hope it helps.
