Yeah, sorry, there is a bug... You have to to go on the headlight tile (on the right in the light world) when the tower 's filled, but in this version, I forgot to link the Win scene... So you won, but you don't know xD i'm really sorry... I've fixed that, but I can't update.
Thanks for your comments guys !! My first 2D art so i was afraid 'bout that. I'm really glad you liked that !
