Played the first version of the game and had a great time with it. tried out the new version and had an even better time, I love Luci, very good chubby alien.
I do think an indicator of what you've already combined(like greying out options you have already selected alongside the first) would be a good addition to make sure players don't repeatedly combine incorrect recipes.
keep up the good work, I cant wait to play the full game.
