I really like this entry. First off all Shalk is perfect and is a good boy. Also the visuals and audio were nice, good sprite work and the UI effects were nice and juicy. I liked that I could target enemies from adjacent grid rows (I guess is the word) so I didn't have to line up perfectly to shoot, it made it more fun to play. The beginning levels having a nice clean tutorial curve made it really easy to get into the game, especially since the mechanics with Shalk were pretty unique. Speaking of which, the smooth tween of the camera going down to Shalks perspective is really cool looking.
The two character mechanic was a great interpretation of the theme as well, and I'm a fan of the cyberpunky dirty subway graffiti bounty hunter vibe, reminds me of like tek war or blade runner or something.
I was a little bit confused as to why Zorgs max health was going up and down as I walked, maybe I missed a tutorial that explained that specific mechanic, and personally I find it weird to use Q/E for strafing rather than turning but that is totally personal preference. I was also unclear if Zorgs tech upgrades reset upon death.
Really strong entry, fantastic work.
