I liked it - and I love that I didn't have to beat a clock just the level itself. The only criticism I have is that it was sometimes difficult to tell which blocks were linked or were turnies and so on - all the red on red on red when one darn block was three different things - perhaps make the playing field and blocks bigger or adding a different color to certain functions would help with that.
Relaxing, simple, easy to play. Basically, this is a game I'll play when I'm stressed and need to relax but avoid other times. I can see why some of the game play choices were made and they do lend themselves to some difficulty to an otherwise too easy to play game (hitting the walls/certain resources after getting the max amount for the level killing you) but it can quickly get annoying. Which makes this a decent 5 - 10 minute time waster but after that (as soothing as the music choices are) the music gets to me a bit...in a nails on the chalkboard kind of way - if the vocals were removed I'd probably like it more as it is a 3 out of 5.
I could keep this game open just for the music, which is just the right tone of creepy as is the glow green writing. The ending is as (slightly) expected (There are only a few people it could have been, after all.) but it does make me want to play more as the storyline is engaging. I look forward to the next installment.
