Thank you for your support!！ However, we have no plan to open donation for the time being, because we are now just students, and we have no way to guarantee how far the game will be improved. What we're doing right now is adjusting the balance, rewriting a lot of "if-else" in the game, and taking your advice to build a webGL version after that. In addition, the current game interaction and guidance is not very good, we are also trying to improve! We will post at both here and LD page if we get anything new！Thanks again！
