Hello Oirchzalet,
I regret to inform you that your map is being rejected.
The theme is original, as we don't currently have any maps based off of "Dominos," so good job on that!
The build is somewhat accurate to how dominos appear; however, it does look a bit plain and flat (I do understand that that's how dominos are in real life.) I maybe recommend adding more colors to them, or at least something new to add a unique spin on them. I also recommend giving them more shape, because at the moment they look very much like pixel art, which is typically not accepted anymore!
The parkour is varied throughout, and the jumps are incorporated with the theme, so good job on that! However, I feel that while the length is alright for a medium map (maybe a tiny bit lengthy,) some of the jumps are too hard for a medium map (Particularly in the beginning there are a few rough jumps.)
Thank you for submitting your map, I would love to see more submissions from you!
Have a nice day,
Kristina
