According to Kat, here's the terms from your sales page she emailed this morning. Where does it say no refunds???
Important: This product is in Early Access status. This means that is not yet finished and may be incomplete in features and/or functionality.
Purchasers will receive access to the development builds as they are completed, and will receive the fully finished product upon release. Please note that although development builds are released regularly, there is no set schedule for their release. Purchase entitles you to the current development build, but does not guarantee the timing of, completion date, or feature status of future builds.
Purchasers are not required to actually test or file reports on the product but, if you should wish to do so, you may use the support forums for that purpose. Bug reports will be accepted (and are very welcome!); requests for changes based upon personal preferences will not be accepted.
We thank all early purchasers for their loyalty. This program enables us to offer a more refined final product while offering users the ability to enjoy the product early!
