so i beat a few levels. paused to try to find out how many more there were. went to menu.. saw nothing for a level select or anything. so i went back to continue and it started me at level 1. some searching around and i found no way to continue my game.
it was at this point i realized that you had overlooked a pretty crucial feature in games like these.
overall it was a fun experience with a nice track and good visuals. i'm a chess grandmaster so it was a bit trivial for me to beat the levels i did play without needing to peek again, but still fun and i can see how this could be useful for players looking to improve their visualization skills.
