Smooth and fun. Land almost anywhere, can shoot any enemy before it darts for you, enemies above behave very differently (nice shooting G2A plants :) ) no enemy hinders your walks for keys and doors. Much more plannable underground walks, nice lava spits inside the volcano.
The minuses so far:
The moon is not in full. :)
Too straight and easy underground caves.
I've managed to walk into the rock and die (when going too far past the door without a key).
I've jumped up-down on the lift (southeastern corner of the volcano) and eventually just fell through it (doing no left-right movement). Maybe it's the AGS engine.
Too small collected items icons.
The inventory limit of 2 is extended to full six, so it's too easy to pass a cave with its 3 items. The casket and pot are also missing, so the volcano and crypt can be done in any order and just once. Maybe using this original trick tasks with added magic springs to replenish magic would do better.
And what about the logo? Doesn't it remind of something?
