BioTiles: A Survival-Horror Puzzler DEMO

Hello out there. This is Jacob Martin, AKA Monokromatik Labs. I've uploaded a buggy, ugly pre-alpha demo of my project BioTiles. I understand that it will be buggy (maybe unplayable?) to many people out there, but I'm pushing this half-baked demo out for my own sanity. BioTiles is the product of months of my time, and I've got few people to share it with an receive feedback from. I would appreciate feedback and encouragement from fellow indie game enthusiasts. Indie development is a hard road. I am a National Guard member paid for one weekend a month, and my wife works full-time as a waitress. Sometimes its hard not to give up, and I feel the need to share what I'm doing in order to keep myself motivated.

Thank you in advance for your feedback, and hopefully you'll understand why I've released this in such a buggy, ugly, unfinished state. Please let me know what you think about the gameplay concept, let me know of any suggestions you have.
