Question: Who published the top-down tile-based puzzle video game that is similar to Hero's Heart?
Context: SpellTower is a 2011 puzzle video game by Zach Gage in which the player creates words from a jumble of letter tiles to clear the screen before it refills.  The game has several game modes and a multiplayer battle mode.  The impetus for the game—the concept of combining elements from "Tetris" and Boggle in what was a prototype of the puzzle video game "Puzzlejuice"—inspired Gage to create "SpellTower".  The game released for iOS in November 2011 to generally favorable reviews.  Versions for OS X and Android followed over the next two years.  In 2017 SpellTower Minutes was released.  This browser-based Flash game created special "blitz" like modes not found in the mobile releases.

The game' s title is a parody of "Super Street Fighter II Turbo" (or "Super Street Fighter II X" in Japan), as there are no other Puzzle Fighter games, and the game includes music and interface elements spoofing the " Street Fighter Alpha" and "Darkstalkers" games.  It was a response to SEGA's popular "Puyo Puyo 2" that had been sweeping the Japanese arcade scene. Chip's Challenge is a top-down tile-based puzzle video game originally published in 1989 by Epyx as a launch title for the Atari Lynx.

Deus Ex Go is a 2016 turn-based puzzle video game in the "Deus Ex" series by Square Enix.  The player uses a touchscreen to move Adam Jensen, a protagonist from the cyberpunk-themed series, as a puzzle piece through a board game while avoiding obstacles and manipulating the environment.  In-keeping with the main series, Jensen can hack environmental features such as turrets and platforms to bypass and eliminate enemies.  The game follows the format of "Hitman Go" (2014) and "Lara Croft Go" (2015), in which Square Enix Montreal distilled major motifs from the games' respective series to fit turn-based, touchscreen, puzzle gameplay.  New to the "Go" series, "Deus Ex Go" introduced an in-game story and puzzle creation mode.  "Deus Ex Go" was released in August 2016, for Android and iOS platforms to generally favorable reviews.  The game was later ported to Microsoft platforms.  Critics wrote that the game successfully captured the cybernetic dystopia of the "Deus Ex" series and the brain teasing puzzles of the "Go" mobile game series.  But compared to the other entries in the "Go" series, reviewers considered "Deus Ex Go"'s to be less creative, with a lackluster story, less visually interesting aesthetic, and shorter length.

A tile-based video game is a type of video or video game where the playing area consists of small square (or, much less often, rectangular, parallelogram, or hexagonal) graphic images referred to as "tiles" laid out in a grid.  That the screen is made of such tiles is a technical distinction, and may not be obvious to people playing the game.  The complete set of tiles available for use in a playing area is called a "tileset".  Tile-based games usually simulate a top-down, side view, or 2.5D view of the playing area, and are almost always two-dimensional. Moebius: The Orb of Celestial Harmony is a video game produced by Origin Systems and designed by Greg Malone.  It was originally released in 1985 for the Apple II series of personal computers.  Versions were also released for the Amiga, Atari ST, Commodore 64, Macintosh, and MS-DOS.  The game is primarily a top-down view tile-based role-playing video game, but it has action-based combat sequences which use a side view, roughly similar to games such as "Karateka".
