very nice gfx, also controls were surprisingly smooth. I especially liked the cover system. I did have a issue with actually attacking enemies, sometimes i felt that i had to find the exact spot to hover the mouse and also felt that the aim and distance sometimes felt off. The chance to hit was quite low even though i was close.
Another thing that was weird was that the main character died incombat but i could still finish the mission, seeing a game over screen after that was a bit weird. I would let the game continue or end the game right when the character dies.
Good job :)
