As others stated, the controls felt a bit off, but nothing which could be fixed in a post-compo version. If you make one, you should also ellaborate on the stealth and surviving mechanic, because that's a really fun part!

Really nice stealth mechanics, and great overall production!

Perhaps turn off the enemies spawning when the player's right near the end? Felt cheap to be killed by something that appears when you're that close. (I've also made a game where this happens :(  )

So to sum things up that need fixing so far:

(also including things mentioned in a few vids) 

• Climbing
• More food
• Jumping after ducking
• Buggy music on chrome
• More hidden ninjas

I like it, loved idea with Martians. I had some problems with the descent of the ladder and sometimes music didn't work on Chrome, but anyway it is really solid!

This was really good. The music and sounds are well done, and the stealth can get pretty tense. There are a couple problems with the controls, specifically with ladders and ducking. Sometimes the player doesn't duck or stand up when he should, and at the top of the ladder he can get stuck until I jump off of it. I thought standing up might be disabled while moving but this was not always the case.

Damn, this was so good!

Some games manage to really give me a fright, this is one of them. Its really involving.

Really sweet game! Super fun! I included it in part 5 of my Public Domain Jam compilation video series, if you'd like to take a look :) http://youtu.be/_BCTeiOyGDE

Very atmospheric. Great job!
