This is actually pretty decent!
The movement is mostly fluent, and you have tons of gameplay mechanics. Spikes, moving platforms, enemies, locked doors, wall jumping, checkpoints, lava… quite a lot.

Sometimes, though, the cat is quite too big to navigate between various perils, so you lose lives quickly and ultimately I don't think three is enough.

The first screen especially feels like a mistake because it's actually the hardest one I found – with spikes that can be avoided only with a well-timed precise jump, after which you can still be killed by the moving platform. It actually made me think moving blue blocks are enemies as well, so I avoided them.
The second screen has an enemy that will always get stuck under the moving platform.

I think I explored quite a bit of the place, and took the checkpoint in the top right corner behind the locked door (why is there a checkpoint in a dead end in the first place?).

What ultimately killed me was wall-jumping where I wasn't supposed to and jumped into a wall from below. The same happened later by falling into an innocent-looking hole in the ground somewhere else. And that's where I gave up.
I think if you want to make something unreachable, wall the area off, and put spikes in supposed deadly pits because this feels like bugs.

Other than that, I'll repeat I was quite surprised by the amount of different mechanics your game offers, it just needs a bit more polish.
