Really cool and innovative game. Reminds me a little about ibb and obb. Just to be clear the ending screen is when you see the two cats with the rainbow right. That end lvl was hard but I managed to win it after some retries. I felt like the spikes that came up from the floor was too fast in my first retries but it is definitely doable. Nice music and cool cats. If you want to continue on this game I would suggest on changing how the level looks like. Grey boxes are not that funny. All boxes weren't aligned aswell and you should either change some levels or the camera or something because there was moments when the white cat was really far away from the black so I would have to wait for the white cat to come back to see something. This happened in the elevator part in one level for example.
Overall cool and innnovative game.
