I'm sorry, but I cannot bring myself to finish this game. Let me list the reasons:
1: The music. I'm not a fan of endless loops that seem to repeat every 5 seconds, and this music is no exception. Thank god for mute buttons. It sounded promising enough, but variety is key.
2: The puzzles. I'm not saying I don't like a good puzzle, but if I have to watch a walkthrough to get through the fourth or fifth level, the instructions need to be just a tad clearer. Also, I see there was a point where you had to jump on invisible blocks. Please don't do that to us in future.
3: Most importantly, the gameplay. Usually gameplay is hard to get wrong on a puzzle game, but not impossible. The mouse interactions were a real pain to do, so much that I relied on the walkthrough not because I hadn't figured out how to complete a level, but because I had to know where to click on a block to get it to fall. I noticed no problems on the X-boxes though.
Minus half a star each for music and vague instructions, and two for the finicky mouse detection.
Now onto a good thing: the storyline. I loved it, and the only criticism I have to make is a very small one: next time, proofread the text for grammar. I'm no nazi, though, and it made no difference anyway. Back to the storyline, I totally related to it. Back when I was 5 or so, I loved my dad more than anything. Now, I'm slowly but surely growing apart from him in terms of interests and taste, but it shouldn't stop us from loving each other as a father and son should. Kudos (plus a bonus star) to you for reminding me of that.
