This is a great idea! and very well executed, great job! 

I like the art, crisp and clear, and the camouflage change of texture is very well acheived.

The guards do not detect "bad cammouflage", right? that could add a lot of depth into the game.

It is a shame it does not have more ranks. In the future, I recommend you to do a WebGL build, that way your game will have more visibility.

Again, good work!

Neat game with a fun mechanic. Movement glitched on me once when I was pressed against a wall, but otherwise played well.

Great came, i like the concept. The art is a little contrasting and hard to see.

Cool game, I like the concept a lot! I think improving the character's movement speed a little would be helpful so you aren't as frustrated having to start all over. I beat it, and it was definitely a challenge so cudos for that.

Cool game! I like the MacGuffin idea. The art is neat, but rocks look like physical objects. I tried to hide behind them and "died". Also, sometimes I couldn't tell if I'm camouflaged or not. Perhaps the default player's sprite should stand out more.

I was a bit disappointed that the terrain you're standing on doesn't matter. I can camouflage as sand and be invisible to the guards while standing on the grass. Otherwise, it's a pretty good concept :D
