Yes, level 49 can be solved, I guarantee it - but it is quite hard, maybe the hardest level of all. If you feel like it, give it another try; you will need to use blue and yellow manholes to prepare and enter and fix the right area.
But anyway, congratulations on solving all other 49 levels!!!
Gracias! Lo que busco con los juegos de puzzle es que los elementos sean rápidamente "legibles" para que el jugador se concentre en resolver el puzzle, y que se maneje bien. Abrazo!
Great game! A fun and demanding platformer, which requires being able to quickly "read the screen" for exits, goodies, obstacles and the way to overcome them. I have managed to complete 100% on my 7th run. Congratulations for this wonderful game!!!
