Short & Sweet. At first I feel really unfamiliar with the controls. But after I realised that everything is in opposite, I know what to do next. xD

It was fun.

The only thing that was tedious was the need to fine-tune the position when going through the gap up one square.

So much fun and incredibly polished, I loved how happy the little guy was every time he jumped. The death sound was mixed slightly too loud, it startled me every time I missed a pixel jump but other than that a very enjoyable experience.

10/10 would torture muscle memory again! Fits the theme really well.

This definitely fits the theme well! You've got some great levels here - a few of them were a little too easy to get stuck on, but it was fun enough to keep going!
