I love puzzle games! Once I figured this one out, it was definitely a great experience. I think 25 levels would really be a fun challenge to try and achieve, and the powerup mechanic is cool too.
However, I do find some issue with the lack of explanation in terms of things like what each barrier or tile does, how to pick up gears, etc. IT would definitely be a major help if you included somewhere in the game page an explanation of or introduction to some of the commonly seen blocks across the map.
Additionally, especially in some screens more than others, there is just way too much visual information (i.e. the screen with like 12 pixelated computers and a power up thing) and it makes it hard to look at and hard to understand. Toning down some colors, contrast, or generally making backgrounds less confusing is a great way to fix this issue.
I had a lot of fun playing this and I'd love to see it a little more fleshed out! It's also interesting visually and I love the crunchy feel it has :) Good job and good luck!
