The game is a box game, modified by onihotBT. The quality of the game is average. I modified it if I was bored. If you like action, you can give it a try. BT content: Experience multiplier, press 0 - switch the immortality switch, the skill release does not deduct anger, unlimited release.
The normal version is available on the homepage. Those who have never played it can go there to read the introduction. I won't go into details here...
