Your game reminds me of Robbox, so I like it
(If you don't know Robbox, it is a flash free (iirc) game, so you can google it, download it, try it, have fun and even maybe find inspiration for your levels from it. Some levels were quite hard )

What is it Hot Dog? I see the screenshot but I am unsure what in particular the puzzle is.

It's a screenshot of the same level.  We were talking a lot about dieing when too close to a bomb, so I just put up a screenshot of the message saying that "you died in the explosion"

That game is indeed inspiring!  (And inspiration is what I need)  It also reminded me that I need to make some easier levels at the beginning of the game.

New screenshot!  Since this is an easier level, I decided to record the whole level (except the jewel) to give you a better idea of what Infiltration is all about.

The game will make much more sense when you read the instructions, but here are some terms you need to know for the screenshot:

* A block is anything you can push around
* A push block is a white block with 4 circles.  They are multi-purpose, usually for triggers or bottomless pits
* A trigger is a black tile with a white circle, something you can walk on (or put a block on) to make something happen
* A keyhole is a wall with a keyhole on it. Keyholes are unlocked in different ways, and usually instructions are provided.

Nice. Just one thing, though: Make sure the level order gradually increases in difficulty in the final version, or at least doesn't instantly go from a very easy level straight to a near impossible one. There can be a few harder ones from time to time but they should be within a certain difficulty average that gradually increases over the time.

Agreed.  I'm constantly changing the order of levels that I designed to make sure this happens.  I only hope that this is an easy level once people read the instrctions.
