Those letters are important! They seem to be in the correct order, but I wonder what cipher system it abides by...
Delightfully charming! I really hope you update this game to include more levels and tighter controls. It felt as if my control over all the Blo people was slippery and they had a mind of their own for a bit. In Level 2, once I got over the red barrier and collected more people, one of the new ones immediately ran into the barrier and died. I know now that you put more collectable Blo people in the level than required, but I didn't know it then and had to reset. Other than that, I enjoyed my time with it! Very impressive you made this in 2 days! Keep up the good work!
