This was very neat. As other people have said, I love the art and atmosphere. The character having the full 8-directional movement was really impressive. I did think it was slightly odd that the pixels of the "lighting" effect were smaller than the rest of the pixels in scale, but it was barely noticeable. I also really appreciated the punchy sounds and reloading on the gun. I didn't really get to use it on anything, but it made me feel a little scared just knowing I had it.
I wasn't sure what to do with the...radioactivity finder (???), which would come up when I pressed the up arrow. It was cool, but it never appeared red like in the game's cover image. I also had trouble trying to escape the lab; checking the page it looked like there were 7 pieces of data, but I really tried to count accurately and thought I had them all and then couldn't exit.
I did enjoy my time with this game. It doesn't seem finished, but I'm glad I got to play what is here--and what is here is impressive! Striker is also a cutie :) A snek?
