Here are my thoughts:
First of all, I've noticed that there are lots of inventory spaces. What is the point in making so many slots when you only have, what, 3 or 4 items?
The second thing is, this game makes me feel like it's a pixel finding game. You have to stand in a fixed place to do stuff. That's kinda annoying, especially in the monster room. I couldn't use the sword on the monster, whenever I clicked on it the message "Hell no that guy is deadly" popped up 'til later when I found the exact pixel. It took me 10 minutes to finally get rid of the monster.
Thirdly, this game gives very few clues. I have no problem with those puzzles but what drives me crazy is to find out what to do with the puzzles. Only then I can solve them, easily.
But, in the other hand, this game has nice and simple graphics that I really like, yeah, and the music, too.
Overall: 3.5/5
