I like the idea, but the execution was not so good in my opinion. The grappling mechanic was well made, but it could be a little faster.
Instead of parkour, there could have been a regular main menu.
I didn't like the music so much, I think an ambient soundtrack would have suited the game better.
The camera is a little weird, but you can get used to it, and the starting platform could be bigger.
The game is nicely optimized and runs smoothly
