I'll be honest, It's not that good, but has some potential.
Art and Sound: The description says "temple", but it's all just some rocks and bamboo in the distance. The spikes are almost impossible to see, I died way to many times to that. Character animations are limited, but I like the "opening doors" one. The music gets repeatable after a while, also door sounds where? Overall lacks "juice". But credit where credit is due, the background artwork looks stunning!
Mechanics: Not very original, but they work well with each other. The only bug I found was the ability to duplicate player infinitly with the soul-splitting green door. Also explaining them through text on the screen is well made tho.
Level design: They're too big. Add on top of that restarting from the beginning on death and you get a massive waste of time. You should add more checkpoints and decreaes the distance you have to walk. Also you introduced platforming in the first level and then it's barely present, only spikes and cameras, it lack variety.
Story: Not much visual storytelling, only single logo of the syndicate,t least as far as I got, that being level with controlling two characters and hiding in blue doors. The writing on the game page is long as a novel and is not very good place to put you game story, it should be in the game.
I'm not hating mind you, just giving some good advice from heart. Good luck on your future endeavours!
