I really loved the game so I will defiitely pinch in as soon as I will be able to. Consider contacting also "blerdyotome", and advertising your game to "otomegames" subreddit and here https://discordapp.com/invite/gYFY5yF (otomegames's discord channel). Show of some funny and romantic screenshots. Mention also your previous games such as "Teachers. With Love and Passion" and "Death is a guest".
Don't be afraid of spamming the discord, subreddits, since marketing is also important! I wish you all the best!
