I really enjoy the different weapons in this game and the way that you obtain new weapons by absorbing glyphs. Different enemies require different weapons but because you can rotate between three active sets there isn't a lot of futzing around in menus. For the most part the proper set of 3 weapons is more than enough for a given level.
If you like 2D action/adventure games this is an absolute no brainer. One of the most fun games I've played this year.
Verdict: Buy it.
