Very nice game! The core mechanics is fun and had me thinking hard a couple times. Very cool pixel art and soundtrack, especially considering you had three days to pull this off. And the dubbing really made me laugh!
I also wanted to report a bug: if one starts a new timeline, then nearly depletes the available steps and goes back in time many times, the steps of the new timeline are added to the steps of the old one (in other words, the steps counter resets to 20/20). Also, you should say in the "How to play" section that moving on the gold tiles does not deplete the steps counter.
Great job, keep this up!
