“Warlock’s Gauntlet/Warsztat Game is an Open-Source community project, created by users from gamedev.pl – a Polish game development site known as Warsztat (the workshop). It’s a dynamic, top-down shooter (well, spell-caster) game, placing you – the player – in the role of a battlemage.”
A quick tutorial + first run. The spells look interesting but the default controls are sadistic. Well worth a look if you were a fan of Gauntlet.
