I think this game has some nice potential, though of course with some room to grow
I like the decision to make the cat charge their jump, I can picture a really cute animation of the cat preparing to pounce, but I hope that the final game has a better indicator of how much you've charged and how far that'll send you (currently it's hard to get a handle on it)
I agree with you that the climbing could use some tuning, but honestly the thing that's stranger to me is... why can this cat climb omnidirectionally?! I don't own a cat, but I'm pretty sure they can't just spider-climb around wherever they want, even on the ideal climbing surface. It feels to me like the cat should only be able to climb vertically, and even then not super well I don't think (like, the cat can scamper up the wall a certain distance, but only so far)
My last note is just that y'all's camera controls are completely busted if you're using a mouse -- for one thing, the mouse doesn't lock to the application or loop around or anything, so at a certain point your mouse just hits the edge of your screen and you just can't look any further in that direction, but the other big problem is that you guys are normalizing the mouse delta; it doesn't matter how much you move your mouse each frame, the camera rotates the same amount (at first I thought the camera had a super high sensitivity, but no, you can swing the mouse cursor from one screen edge to the other and get the same amount of camera movement as if you had only moved the cursor a few pixels)
