I think I don´t have to loose many words about one of my all-time-favorites "Bubble Bobble". You play the two little dragons Bub and Bob and guide them on their journey through the cave of monsters. So you jump over the platforms, bubble in all the monsters and destroy them afterwards by touching the bubbles...
Sounds easy, is grat fun and after all the years (about 20!) it´s still a game I like to play.
This one is a 3D-remake of the original. Everything has the spirit of the original (design of monsters, sound and music etc.), so you can see the developer truely loved the game as well. Only negative point ist that there is no 2-Player-option.

I think it´s freeware (at least you can find it on several freeware pages), but I´m not 100% sure. Unfortunately I couldn´t find a mail adress of the developer as well...
