Hey there!
Thank you very much for trying the game and taking the time to comment and let we know your opinions, feelings and suggestions. I appreciate it so much.
Regarding increasing difficulty with time or after tot energy, it's something we already took in consideration, level design must be tweaked for better enjoying it.
Yet I hear a lot of people not being able to complete it easily as well, so we are gathering all info and then think about which direction move.
Thank you for your kind words! It means a lot to me and the team!
