I tried the game, reminds me of bloodthief mechanically, it was fun and the theme is funny but as a parkour game enjoyer myself i need to point out some flaws of the game.
Running should be the default speed, the slam should not remove all your momentum or at least it should let you control it as it is very easy to fall into a pit, there doesn't seem to be any coyote time to help you jump off ledges, and you can wall run multiple times on the same wall.
Aside from that the game could use some QoL like auto attacking when rushing, ignoring the enemies debris collision and some game settings.
The base is there, although polishing these kind of games is quite difficult it can make them very enjoyable.
