Press flag twice. Use arrow keys to move and space to jump. Try to go through the obstacles and if you liked leave the comments a liked and a star help a lot and part 2 could be released, ok? If you happen to see a grid going up and down on the first level click on the flag again as it is just a game bug but if it appears on the second or third phase it will be normal.
Project still in progress and if this project reaches more than 15 hearts and stars, a second part can be released. Per: @TobeComputer Below I will put the date of the last update 10/11/2021
