I love visual novels, from steam to mobile. But this is... Meh, the reason being the energy cost for going to sleep. If you ask me you go to sleep to regain energy and use energy when battling. That is what I would change. Use energy to either make decisions, or use energy to train, plus money, use energy to do campaign. It'll add more strat. Another thing is the gems... (Update) the good endings cost gems. So if your looking for good endings, you have to wait a whole month of savings gems
