Along with releasing Double Fine's Halloween RPG Costume Quest today, the latest PlayStation Store Updates features two more PSone Imports from MonkeyPaw Games: Warashi's shoot'em up Shienryu and Open Sesame/Techno Soleil's puzzler Tall Unlimited (video above, also known as Tall Infinity).

Arcade Hits: Shienryu - Shienryu is a classic vertical-scrolling Arcade shoot’em-up. The game can be flown alone or with a friend for added power (and laughs!). You’ll face off against towering alien mechs and endure a bedlam of bullets that will test your steel.

Tall Unlimited - Tall Unlimted is a challenging puzzle game where you build a tower by rolling blocks so the colored sides match up. Matching a block creates two new blocks. There are chain reactions and combo moves to strategically elevate your game. The object is to build a tower as high and fast as you can. Sound easy?

Both games are priced at $5.99 each ($3 if you're a PlayStaiton Plus subscriber), and are presented in their original Japanese language. MonkeyPaw has so far taken care to select games with little-to-no language barrier for its PSOne Imports, though.
