This was a unique take on the theme and reminded me of fireboy watergirl. Now let's start with the good. This game really sets itself apart as it's concept uses two characters that you can control and bring together. Having the momentum continue when switching was great and the blocks only being there in 1 version was a great puzzle touch. I really liked the way this was portrayed it was very clear what was happening at when moment. The bad is that the art didn't appeal to me, it felt a little cheap to me but it still made it's own style thus I could enjoy it. I had some issues with the scaling. The first level is very tutorial like helping me understand and getting there. But the second level immediately scales with saws, parkouring and harder things and that's kinda difficult and needed a intermediate level. I also found out that if you jump to the side of walls and spam the spacebar you fly up into the sky. You can also get yourself inside block by switching then spamming spacebar and switching again. You'll fly up as well. The camera system was difficult as at the last level I couldn't control the second person on the outside of because the camera wouldn't go up even tho the inside person was at the top so I sadly couldn't finish and for some reason the person outside felt like he didn't want to live and threw himself of the platform whenever I was the inside character. Besides these issues, I really really like the concept. i think it's unique and with more time, polishing and levels this could be a great game. Nice job!
