God dammit, it's working! And you know what?! Because, in my translation, I confused RED and YELLOW, so everything works until that moment with flower :D Aaaaaaa... Anyway, I'm now in day 47 :) Thanks for your help.
Any chance you would fix checkpoints, maybe updated the game to final stage as you wanted? Cause I would love to buy it, download it and play it in my free time and let my daughter and wife to try :D
