Hello, I'm Runinzem, in charge of game design and art for this game.
A lot of users have voiced their dissatisfaction with the leveling up system that was changed in the 0.2.0 update. As a result, we are planning to roll back the leveling up system to the previous "temporary level up system" as soon as possible.
The current leveling up system needed additional content and elements to be structurally complete, but the 0.2.0 patch left many features missing due to time constraints. We decided that it would be better to roll back to the existing system and add the content we were originally going to include, rather than have users continue to play with the current uncomfortable system until the finished update is ready. We apologize for the inconvenience caused by the incomplete patch.
Once this structural improvement is completed, we will begin working on the level up system rollback as soon as possible, with the rollback expected to take place within the next week. Thank you.
