I found a game whose idea is similar to mine! Though, I would suggest improvements in the mechanics of the rope. The rope is very springy which makes swinging a lot harder than it has to be. Despite about 10 minutes of trying, I couldn't even get past the first level which is sad. So, the difficulty curve could've been improved. I'm happy to see a restart level system implemented here. The space bar seems to make the boxes change color but I didn't find its application described anywhere.
Summary: Happy to see comfort features such a restart level feature but the mechanics need to be executed better and the difficulty curve needs to be addressed.
