This is an autobattler game. Dropped the game after I reached chapter 2.
👍 Pro: No bugs encountered so far.
👎 Con: The only player input is pressing the merge button, provided you collected enough monster parts.
👎 Con: The battles themselves become boring quickly as you have to watch the same animations over and over again.
👎 Con: The monster parts mechanic is basic; some have special powers and many are just stat improvements.
