Solid first mission, that doesn't risk too much. Good architecture and level design. Not overcrowded with guards, which I appreciate.

Things that could be improved in my opinion:
- City or any other landscape in the background / horizon is missing. If you get up too high that as unfortunately a total immersion breaker.
- Design of some of the unreachable buildings, and some areas outside is fine, but maybe a bit bland.
- Story is very basic.

Overall I enjoyed the mission, and I think this is a successful first attempt! Liked the jokes ;) Thanks, keep it up! :)

Ah, btw, personally I'm not a big fan of the pixelated texture style, but yeah, that's just a personal preference.
