This week's trailer roundup features a multiplayer dungeon crawler in which players play both monsters and hero, a digital dungeon crawling board game, a Japanese RPG (from Japan) with a very non-standard battle system, a match-3 game that appears to be a survival sandbox game, a midieval themed shoot 'em up, an action RPG focused on storytelling through exploration, an arcade-ish runner-ish game which tests player reflexes, and a visual novel/dating sim headed by a female character leading an army during wartime.

Windows, Mac, Linux | $9.99 | Early access

A local multiplayer dungeon crawler in which all but one person plays the monsters trying to kill the hero. Killing the hero makes you the hero, so players are constantly competing to be the person to take the hero up against the procedurally generated dungeon's boss. Developer Powerhoof is interested in adding online multiplayer capabilities.

Windows | $ TBA | Winter 2014 (Steam early access)

This one is a digital multiplayer dungeon crawling board game that takes inspiration from Monopoly, Diablo, and Hearthstone. A Kickstarter is planned for September and launch on Steam early access is to follow soon after. Although Dicetiny will begin as a Windows-only release, the developer intends to expand to Mac and Linux in the future.

Helen's Mysterious Castle
Windows | $1.99 | Available now

Helen doesn't know much about her past. Stuck on an island with a mysterious, labyrinthine castle, she decides to start exploring it. This is a JRPG with a non-standard, not-exactly-turn-based battle system. Helen is the only party member. She picks up various weapons along the way, each with its own offensive stats, defensive stats, and battle time cost. Using a weapon takes a certain amount of battle time, during which the enemy also attacks and at the end of which battle pauses to allow the player to choose the next weapon to use, allowing for changing strategies on the fly. This trailer is in Japanese, but the game is available in English.
