At first I was like, what is up with two cats, then I realized you have to control them in tandem to get them both through the level. Wow. Brilliant! I'm glad I came back now that it works.

Saw this game earlier into the ranking period because of cat but was disappointed that it didn't load. Im glad you were able to fix it. The game is really nice with good art, animations and music. The gameplay looked simple but with 2 characters it was more puzzling. I made it to the end with the heart. 

I like this puzzle game.

Simple but still enjoyable.

From downsides - when cats are moving they begin to jitter. Probably some problems with camera.

But in overall good job.

couldn't load project data at path ".". Is the .pck file missing?

Looks like just the exe, you need to include the whole build directory
