(I am now in a rush to test as many games as possible to help, so please do not mind the cursory reviewing style.)
Semi-on-the-fly remarks:
REMARK: first game I test from the special page for submissions with few votes! (The previous one, "Punk", was not easy to download and had a suspiciously early publish date.) I usually use it, but went for Karma, this time. TIP: review other people’s games to spark interest! Including getting higher on the Karma ordering, which depends both on your comments/ratings given and on the ratings you received. ;)
- Controls are QWERTY-only instead of layout-independent (I have an AZERTY keyboard), BUT arrow keys are enabled.
- fast movement
- shadow: so, we are some kind of giant pill? ;)
- Oh, knocking some things down, I notice the spheres become ellipsoids when rotating! :o Is this on purpose? Like, a non-Euclidian world? X)
- Feels like a playset with things and persons to make fall! X)
- Jimmy Neutron?? Feels a bit out of place! Or I did not get something, or you planned some specific story.
- Ah, you can jump with Space! And crouch with Left Control. You should mention all controls on the game page, I think.
Takeaway: I agree with Delldone9831 that the game seems unfinished. I agree with his wise comment. One thing I can somewhat judge is your take on the theme: choosing zombies falls into the category of those games that chose a ‘horror’/supernatural element, so this is quite classic, but fair.
Keep on enchancing your idea, footstep by footstep. :) A French developer teaching video game development (David Mekersa) calls looking at the big picture without seeing that you can take on small steps the ‘mountain complex’; not sure if the term is idiomatic in English, but you get the idea. ;)
