BioTiles: The Survival-Horror Puzzler Windows game

Lately I've put a lot of time into revising code and implementing proper turn-based procedural flow. I am also reworking the health and infection meters as well as other interface elements. Over the next few weeks I intend to release a polished demo of the first few stages! Most assets for this are finished already, but the first stage involves some heavily-scripted hand-holding to introduce new players to the basic mechanics. Here's a brief overview of how BioTies plays:

• BioTiles is a turn-based puzzle game with RPG and horror elements.
• The player swaps adjacent tiles to make matches of three (a mechanic familiar to many).
• Unlike other puzzle games of its ilk, BioTiles features its player character as a tile on the board. This forces the player to manipulate her position in relation to her foes in order to avoid damage and utilize her weapons.
• An item introduced early in the game is a severed hand, dubbed Zombie Bait. This item allows the player to change the direction tiles shift in once others are destroyed. This is what adds significant strategic depth to BioTiles, as it allows the player to plan combos several turns in advance.
• The player will take damage from nearby infected and must defend herself by scrounging ammo (by matching scavenge tiles) and patching herself up (by matching medkit tiles). However, each stage entails specific objectives, and the player must hurry to complete them before succumbing to the airborne infection.

I am currently working on BioTiles full-time and would love to hear any suggestions, feedback, and questions you may have. Thank you for your time and for your support!
