We both thought of the same thing: scaling a tower with difficult controls!
Initially, the game was difficult, but the more I played the more I learned to control the character. It was pretty fun just swinging around in the beginning section of the game, although the game ramps up in difficulty a little too fast, so I suggest either removing some of the spikes or making the space between them bigger. Also, reducing their hitbox size to half will make the game seem fairer to players because touching a single pixel and having to restart is frustrating, in contrast, entering a quarter of the way in a spike is clearly the player's mistake.
The game is clearly going in the right direction and, with more time, you could refine the level and add some quality of life features such as separate sound and music volume sliders and sensitivity sliders.
