Heya Lei,
Glad to see another map from you! I'm going to give this map a "+1". The theme is 100% original, I haven't seen anything like it before. The build resembles a barbecue to the T and has that as it's main focus, it's not messy or contains various useless parts. The parkour length and difficulty definitely fit the medium difficulty and I found it quite varied and fun. Job well done, I hope your map gets accepted!
