Key's Curse [Puzzle] - Looking for Testers

I'm looking for testers. "Key's Curse" is my first game so I went for something small - only 4 main screens.

The core idea is that everything is either a lock or a key (or a giant black urchin waiting to kill you). So you need to choose keys in the correct order to open the mega-lock.

Since it's my first game, I'm not sure how to classify it (hardness/action/puzzle/whatever).
I'm also looking for advice about playability, music, cutscenes, etc.

I'm hoping to post this game soon. Just looking for a few testers. Anyone interested? 

UPDATE: It's done! Things were starting to spiral out of control...I started with 4 screens and ended up with three difficulty levels spanning 57 screens. Now I understand why people have 400+ screens...

Thanks to ultigonio and green.cookie with their wallswim advice and other ideas.

Anyway, here she is. Just copy the url into your browser address bar. It should work...

It looks very nice, it brought new ideas to KS world.

And if you want me as a tester, I am in...

Oh my.  This looks quite interesting, indeed.
I'd love to be a tester.

Look at all the keys! I would like to test.

I'd LOVE to test! This seems cool!

Was there any actual testing..?

Was there any actual testing..?

Ha-ha, yes, there was plenty of actual testing.  Wallswim help was one of the bigger things.

I only played the easy, but I thought this was really fun.  I just didn't have the patience for the others. 

Haha - ya, I have a hard time judging difficulty. I'm good at puzzles and terrible at jumping challenges so you have to take my difficulty rating with a pinch of salt (and a shot to tequila).

I have a partially completed redo of this level with an easier easy and a harder hard. But I also want to make a traditional environmental level so I'll probably do that first.

Yeah for environmental.  I'll keep my eyes open for it.
