Played the demo, and here is my (short) review
The Good-
>I liked the 2d artwork of the game, nice job with that

>Level design was GREAT, I can see that you've carefully placed entites, instead of just throwing em around

>Music was good, but it was a tad too loud
>The enemy placement was nice, but the gameplay couldve been a little bit better
The only thing I didn't like was the use of the light overlays.
In my opinion you over used them a bit, and in most of the battle scenes I couldn't see the enemy cause I was blinded
Apart from that ^ It was a great little demo, looking forward to the full release!
I give this demo a 4/5, because I loved the level design!
Great job Leon and Polofleece!
Boom.
