In this game, you can explore through M (random map) to obtain crystals (suggestion) or kill bots to increase your money. When you have enough money, you can increase the value by using Q (the probability of summoning thunder to purchase sword weapons) or X (increasing the health limit). The core level of this game is S (Boss Battle), where you can challenge them at any time by using weapons (1. SMG, 2. ShootGun, 3. Sword) and some operations (press E to avoid damage when startled or use left Shift for some boss attacks) to defeat bosses. The above is the current version of the game gameplay.
