This game is a unfinished jewel! it keept me running for about 1 hour. So it may be short but well written. while playing it felt like i could actually explore on my own, without knowing the exact path, that motivated me that much that i could not stop until i finished. the shooting enemies can target you by aiming, while fighting i thought "I wish i have a module that allow me to acually target them"
graphics and environment 7/10
the design could be improved but might destory the flair, but the colors might need some minor tweaks
controls 8.5/10
jumping with the head hitting the roof feels wierd and not intended
i missed to listen to the music so ill skip rating this
puzzles and story 4/10
the puzzels are not complicated and the story does not offer much but the gadgets give you some power and something that keeps you running
Everything together i would rate this a 8/10
(+1,5 as i think that this has a great potential)
think about giving it a wider background story. some optional dialogs would increase the glare of the game. the end were a bit rought. another round or chapter would be wonderfull. althought a area beneath the city might fit here. take a look at the netflix movie "Blame!" the environment reminds me at the tube area. an area that expands throught environmental changes althought might be a thing.
