Welcome to Weekday Puzzle!
The first game with letters by rubyleehs is fun and you can spend A LOT of time with it - notice, that it doesn't have a save option so reserve enough time for it. Then comes a beautiful ethereal labyrinth by jcGyo where you got lost and need to find your way through. The last is very unusual platformer by baba_s where you don't need jumping skills much - creative mind is more important.
Have a good time and enjoy!
