the change in engine is more than understandable, sucks you guys had to essentially rebuild the game because of unity being a greedy sunovabitch, my deepest apologies for sounding rude in my previous reply.
about what I didn't like... firstly this build is clearly way more unfinished and less polished than the first alpha, the game runs worse and theres no way to tone down the motion blur, or the excessive bloom, nor does it go fullscreen like the previous alpha.
the goldeneye-esque aiming is cool, but is useless if the player gets swarmed by enemies (they dont even react differenty based on where you shoot them), the previous alpha had a more quake-vibe going, why change that?
personally, the modeling and texturing was more charming in the previous alpha, from the weapons to the characters, hell even the hud looked better in the previous alpha. in this alpha everything feels almost more... highpoly? idk
the level design isnt bad, but small things like the statue giving you guns, the room setpiece near the end of the first alpha, and other stuff are all just missing.
overall I was a little disappointed by this one, I hope I didn't come off as pretentious, but I've got high hopes for this game and I really do wanna see it bloom into something awesome
