The Wizard's Lair is a roguelike with roots in the Classics and Mystery Dungeon series of roguelikes - procedurally generated levels, many monsters and traps, powerful weapons and secrets to find on your quest to destroy the Wizard of Anarkhis!
Wizard's Lair is a good roguelike to give it a try but there are things that didn't keep me going.
Graphics could get a bit better - some wall & floor variations wouldn't hurt as well as some eyecandy stuff.
Interface is a bit confusing before you get used to it which includes navigation through your inventory and all.
Gameplay is a bit too linear and straightforward for me which is not necessarily bad - roguelike newbies may find this game perfect to start with.
If you ignore all this, you'll find nice time playing it - there are quite some items, spells & potions to play with as well as many levels featuring different enemies.
