English translation is now completely done - thankfully I managed to hire a native speaker to do the proofreading,
There was a problem with resources due to the 2k BGs and live2D. Now game runs on the almost any PCs with more than 2 GB RAM (don't forget to turn off other apps if you face some problems).
Bug with double phrases (some phrases appear twice) is fixed.
Update 1: English translation, resources usage, minor bugs
