Neva is a futuristic hybrid between an action platformer and an action puzzler.
Each time when you have completed the platforming stage (in which you jump, fly, fight and run) you get to the puzzle segment. In the puzzle stage you have to hit the right buttons at the right time…
To understand the gameplay mechanics i highly recommend to play through the tutorial before you start the game.

The game has overall great production values and features really nice animations, futuristic graphics with fine effects, an original soundtrack, nice cut scenes which drives the story further and a nostalgic HUD which reminds of the good old Amiga days.
