I've loved the full version of this game and unlocked everything. It's a delight. So much attention to detail in the UX. The final unlock is funny, too.
I'd like to see a list of the trophies because there one or two I never quite figured out the meaning of.
Sometimes randomly generation makes a puzzle that is unintuitive, in that you need to avoid a lot of efficiencies in order to solve it. I'll often use hint mode for those, and the solution can feel a bit iffy sometimes (though sometimes it's "oh of course, I should have tried that"). This is always the case with generated puzzles, of course. But it makes me wonder if people have handmade some clever puzzles. I wouldn't know where to look, tho.
