Frog Tactics comes from Guillaume Danel. The object is to place arrows and jumping points to make the frog hit every square and then land on the red spot.
Of the 60 regular levels, I've solved 45. The game allows all users to create their own levels and share them. At the moment, there are 360 of those.
Very interesting: you must place directional arrows or a jumping icon on various tiles. There is also a 'go back 3 steps' move.
