Cool concept and combining of 2 themes ^^
I like the gameplay's simplicity where it's just move around rescue people and reach then end of the level.
The sprites look really good as well, and i really dig the music of the game.
I didn't have any particular issues here, though i had a funny moment (and i suppose this isn't intended) where one of the refugees was just there chilling with a trashcan stuck on him and as soon as he hopped in the mech the can just flew away :p
Overall had a good time trying it out, good job to you guys :)
