Cavedroid

I reviewed Cavedroid in the past as a footnote on one of my Freebie Friday sessions and expressed disappointment. At the time the game featured a 3D perspective, but only allowed up/down movement. I preferred the side scrolling SFCave (and knockoffs) over this 3D cousin. The author has since been hard at work and has added 2D movement making the game far more interesting and separating it from games like SFCave in play. This in turn has made the game much more interesting and enjoyable and it is now a recommended title especially because it's free. Well, not entirely free... the author is taking donations on his website so it's up to you to pay if you enjoy the game and find yourself playing it a lot.
