Its a great game
But i think it could get some adjustments near the end. Level 13 is insanely difficult imo, so i'd hate to see what level 14 is like. It needs to many specific toys to attack a certain enemy, and the at the rate of generating fantasy compared to how expensive the toys needed at the end can be and how fast the enemies come, it's just too much. The amount of times i wished for an alien that could shoot in the three rows and hit fliers was unreal =P And i hate those skeletons... they kept targetin my books. Once they appear and start taking ur books, u've pretty much lost the level.
Without dumbing down the intensity of the enemy respawn, u could probably make toys that little bit cheaper, make the books generate a bit more fantasy, have a third book to generate a bit more fanatsy than the image book (i don't count the 3d book, don't like that one at all) or perhaps make the board a bit longer so u have more time to deal with things.
Anywho, its a great game and i'd look forward to another
