I get this error.
Is that because I'm using a 32 bit version of Windows?
Ok, I had some spare time and built the game for 32bit. Haven't had the time to build the installer though, so you'll have to run the exe in the same folder as the data folder and the unityengine.dll file. Just extract and run ReTech.exe in that folder, and you'll be fine.
If it still doesn't work, please post here or send to retechgamedev@gmail.com the file called output_log.txt located in "Appdata/LocalLow/Helix Creations/ReTech", and I'll try to fix it.
You don't need to worry anymore now, I have built an installer for 32 bit as well. You can download it in the download section (file called ReTech 1.0 (Windows 32bit)). I didn't have the installer a few days ago, so there you would have had to run the exe in the same folder as the data folder, which contains all the game data necessary to run.
