It's been around for quite some time now - say, 20 years - on various formats, and now Jamie Woodhouse's recent PC release of Qwak is half price over on Archive Games for the next few days.

Qwak is a 1 or 2 player platforming collectathon affair where grabbing fruit and gems while dodging falling spikes and strange, fish-like creatures is the key. As a single-player experience it's pretty solid, but whip out a friend and you could both be stuck at your keyboard for a rather lengthy amount of time - the gameplay is simple, addictive and jolly good fun.

Check out the Qwak site for more details on the game, download the demo to see what you think, then head over to Archive Games and grab it half price now.
