Surprisingly great! The initial impression wasn't that great: graphics were clearly recycled assets I've seen used everywhere and the presentation was a bit bare-bones and lackluster. But I pressed on, and I'm glad I did, because the puzzles in this game were a lot of fun! Game had a very unique concept (though I have seen it used in some games like Toodee and Topdee) and it used it to great effect: slowly building up the challenge and mechanics bit-by-bit, explaining just enough that you get the gist, but allowing the player to connect the dots and have some incredible revelations. Like I say, some of the general elements like graphics, sound and music are lackluster, and the controls can be a bit wonky at times, which drags the game down a bit, but the game design here is very solid and impressive: would love to see it revitalized with some polish!
