We found some unexpected bugs before release. There were problems with the input on the computer build, but we never saw them on the actual app. We could simplify the testing on multiple platforms, so we decided to release it how it is, and have some testers ready for when it releases. If the input problem proceeds, we will fix it immediately.
The app will be availeble as soon as possible for 0.99 Euro on the PlayStore. We will also change it to free in the far future.
