Music is nice.
When climbing onto a Ledge ( no Idea why you trace so high to find one) and climbing back down you get stuck in the Wall.
Your Animations for climbing also clip through everything heavily and look odd.
When trying to get unstuck again I teleported ontop of the House, skipping the Tutorial.
Is there any Point in blowing Bubbles apart from it being Fun?
Your wall climbing sometimes rotates in wrong Directions, I'm assuming it hits the Ceiling. It also doesn't work on diagonal Ledges. And either only the small Girl can grab a Ledge, or it doesn't work everywhere.
Your Guns don't hit anywhere near close to the Crosshair.
The Idea with Weaponsize/Charactersize relation mattering is great. You can change Weapons while in the size-select Screen, without the Screen clearing, or your Weapon being displayed differently.
You can try to climb the not perfectly aligned Floors causing horrid clipping again.
