Good ideas, for sure.  Something to cancel auto-jump while holding down jump button might be good.  Trying to jump onto platforms that are two tile above the cat are tricky and it seems glitchy when it does happen. Other things like multiple levels and  a proper ending might help out.

So fun! I'm the exact target market for this, I wish there were more levels!  I love the free-form wire mechanic and having both WASD and arrow control options.
