Basically a pinball game with RPG elements. It's quite simple, as players launch the ball, break the walls until they clear a path to the enemy monster, and defeat that monster. It's quite a unique concept to be honest, and not one you will see in a lot of games.
While the first few matches are quite nice, unfortunately, the novelty will wear off. The game will get stale as players progress, with "battles" becoming repetitive. It does pick up whenever bosses are concerned, but all the grinding makes the game quite... meh.
Overall though, it's not quite a bad game. They just need to up the variety and difficulty a little bit, because as it stands, the game is a tad bit boring. None the less, this game has the potential to be quite good, and I hope they add more difficulty to the levels and up the challenge.
