This was fun. I really like the fact that the screen changes when you rewind. The puzzles also were interesting, but I felt like some of the first puzzles were harder than the last ones. Although it took me some time to get level 6 right. Overall it was a fun challenge, the music was good and made it more fun.
Also, I didn't expect that there would be that many games with slimes in it, mine has one too! You could check it out if you're interested :D
