Wra'khata from B.V.B.
Three levels with a minimal mission. The spelling & grammar are so bad it's awesome. Don't think it is an English thing but you never know. Good Opening Screen/Music with first term telling you "you will have to extinct the . . . . " Read Me says hard but fun. First level, do everything 5x's but term to transport out-of-order. Second level a prison & you may transport to level three wherein if you don't get the order of the switches right, dead end room/done. Pattern Buffers available and a great assortment of baddies to cream.
