I like the low poly design, and the city looks cool. Wish I could explore more of it!

Some feedback:

• Have the player start facing the direction they should be going and not toward the elevator.
• It'd be nice to have a controls screen. I kept thinking I could interact with the elevator buttons, but nothing I tried worked and it'd be nice to know that's not actually possible.
• A more traditional main menu with a start button might work better. It took me a minute to figure out that you have to hit ESC to start the game.

Interesting!

Forgot to mention, press tab to pause/unpause and start the game. That seems important to know.
