Amazing!
Great result for a game jam game.
I had the problem too to toggle full screen, so I run it in window, but couldn't see well where I was aiming.
In the end, even if I tried hard with the gun, I found too that the best weapon is the punch, or better jump and land with double punch on the enemy for instant kill!
Nice glass effect for the swinging door at the entrance, nice building fading to the infinite and nice street where you come from. I tried to go there, but I couldn't, it was really inviting to see how it was made.
Escalator effect is super well done, and aside a few glitches, the game ran very smoothly.
Definitely a game that can prove that Construct can make fun old-style 3d games!
Great accomplishment!
