The visuals on this game were really good, I liked the character models and the lighting. It's clear you put some thought into how the game should look, and it's great you were able to create a gameplay video, it really helped with figuring out what to do.

I do think the gameplay is lacking  a bit, and it's also missing some overall polish. Controlling zombies to attack attack another create is a neat idea, and moving between zombies is smoothly implemented. There just doesn't seem to be that much skill involved in actually playing the game - move to a zombie, attack Igor, die, move to another zombie. I couldn't really tell if anything negative was happening to me if I did or didn't attack him, and there was no strategy involved in attacking as most things seemed to be done automatically.

In terms of polish, the little animations were a nice touch and I thought the lighting for the scene was really well done. I would have liked a main menu or pause screen though, as quitting the game and then launching to replay is a bit of an annoyance. In your case it would have been fairly simple to bind a key to a restart method, or have an overlay UI that had quit and restart buttons, even if you didn't have the time to design a cohesive UI.

Overall I think your idea was pretty solid and visually the game was good, but it lacked gameplay and some basic polish. A good submission though!
