Great experiment, but...
Let me get this out of the way first: This is the most fun I've even had on a flash game
Controls: top-notch (except for the dash, considering there's walls and enemies everywhere i could never find a good place or reason to use it.)
Graphics: Loved the style, but the final cinematic was, Meh.
Sound: Great, no problems with them.
Gameplay: It felt odd not having an attack button. Once I got past that though it was a blast.
Other thoughts: The boss was horrible HORRIBLE HORRIBLE! (say it three times to have greater impact)
The "Kill the boss with his own attack" is about as creative as the start button. Not only is there no initial hint on how you're supposed to kill him, there's actually very little buildup to him. Instead of eerie music coming up when nightfall comes in order to give the player a sense of dread and fear it's simply "here's a boss, now you die."
The guy character: I am not going to think that two people are in love simply because there's a text that says so. You want us to believe that they love each other? Either let them have interactions together or scrap that idea altogether.
The level up mechanic: I didn't mind loosing all my levels at the beginning of each day. I would have preferred a larger emphasis on other things however. Like, for example, the water jump. As it is it's useless, but if it was capable of sending you to new areas even while you were lvl 0, the game would have been far more enjoyable. Turning each area into a race against the clock would have given an interesting twist on things, and it definitely would have given a reason to play past the frustration.
The ending: You remember all the people who rejoiced at the cliffhanger of halo 2? Me neither. I already said how much the interaction between the two characters was underwhelming so I won't repeat myself.
Overall this review was much harsher than I initially intended. But if a sequel is in the works I'm really excited to see how much of what you've learned in this game will be added to the second.
I really want to put this above eight stars, but there was too much room for improvement.
