The game is done very well, graphic is beautiful and battle mechanics is interesting. But I think before the Crystal boss you should add a warning or some kind of...healing? to make sure the players dont go there and fight the boss at low hp (I was there and liked "Well I guess i will load my save file and heal my party" then I realised my last save is 20 minutes ago so I fought the boss anyway, struggled through first 5 minutes without notice the gimmick and somehow managed it) and in the last city (sorry I cant remember its name, my memory is kinda bad) there is a house let you rent room (inn?) still have German for the Yes/No choice.
Keep on the great work :) I am looking forward chapter 2 very much and I hope more people will know about you and your work
P.S:English is not my first language, so Im sorry if there is some errors.
Edit:I usually get error message "rgss player has stopped working" when I first played the game, after run the Game.exe in bin (in bin, not Launcher.exe) in compatibility mode Windows XP (Service Pack 3) and run as an administrator, it seems to be working fine now. My system is Windows 7 32-bit so I think it will work fine if you have this problem.
