Solid idea with a wonderful execution.
The art was great. Very gritty and industrial feel. Lots of parts of the level had a weird scale compared to the main character that made me feel like I was controlling tiny robots in a much larger area.
The music was exciting and catchy.
I found that I was repeatedly forgetting that the sound effects were done with a person's mouth. I'm not sure if that's because the sounds were so good, or if it was because the gameplay was engrossing.
The character model and animations were good. The blood effects got the job done.
To find things to criticize, I'll have to get really nit-picky about it.
In some areas, the walls were big empty planes, combined with some relatively long hallways, it creates some deadtime that could probably be more interesting.
The electric spark effect could have been a lot sharper with very little effort. The blurry ball particles caught my eye and stood out.
When I bumped into a wall to flatten out my minions, it was often difficult to try and get them to go back out in a direction, so I tended to travel in a tight ball of dudes. This lead to me struggling to figure out how to set off the squish traps without getting killed myself. Though maybe that was just me doing something wrong.
Great entry though. I really liked it.
