Awesome game. I already enjoyed playing “SkillTeam” and this title has given me such a good time of escapism. As a way of suggestion, you could have hidden the level titles (since they provide a good clue to solve the puzzles), only to be shown by clicking a “Hint” button on something like that, or implemented an Easy Mode in which the titles are shown, or hidden on the contrary. I have solved many a level a bit easier just by reading the title. Although, on the other hand, they (titles) add to the gameplay.
Congratulations for the game.
