There are a few issues with this game such as when I click on a difference, sometimes it won't change if I click on one picture, but it will change if I click on the other picture. (Especially for smaller differences)
On the starry level, one thing to note: The lines, if they show up, are not one of the differences (even though they are different), they appear to be a bug. Second, do check the stars (the stars should really be a little brighter so that you can differentiate between say a dead pixel and an actual difference).
Having trouble with two achievements: Hit a shadowdemon with a thundercracker. I hit the big demons and kill them in one hit, the achievement doesn't work. The next one is the melting snowman. Having a hard time to get it to melt. It dies, but doesn't seem to want to melt for me. Anyone have any luck?
Considering I play Touhou, this game was fairly easy. Not saying that is a bad thing or a good thing, but I'm pretty sure most people are used to games like phoenix where you have a high speed 'shotgun type' attack area.
I can hear my character going: "These guys that make these missions up must be sadistic people who want to see me struggle. I'm killing a clone of the same person over and over again with the same cloned guards." And he is just thinking: Why don't they just let me kill the people at the cloning facility and get it over with?
