Polaris2013: Throughout the game you find powers like "ability to turn left" and "HD textures." Is there any way to track which ones you have unlocked and which are left to find?
I ask because I had 95.6% completion when I finished the game even though I found all the stars and cards, got the chocobo/merchant item, and beat champion level card game. That seemed like everything. I'm guessing there must be some other chests I missed somewhere but no idea what they are or how to look for them.
This is a pain. This is one of those games that's so reliant on Steam that it has no support for its own achievements - that's bad enough on GOG but this game is sold from the developer's website and that just makes it doubly silly. Your best bet will be to check the Steam Achievements and try to remember what you do and don't have. If you aren't sure, try it again.

You're probably missing the petty achievements, like Sniper, Exterminator and Takoyaki. You may be missing Hoarder, Undertaker and Turtle Soup (I think the Diablo section counts for Undertaker). If you need to refight the Noria boss, there's a switch in the boss room.
Lastly, I see you have it but if someone else comes along: it doesn't seem that there's a Steam Achievement for the meat/merchant subquest, so do that as well. That should cover pretty much everything.
EDIT: You may also need "Full Metal," the in-game but apparently not Steam achievement for getting all of the pieces of useless Diablo equipment. Easily checked, just go over there and pull up your inventory.
