### 5/5 — Good

*2025-03-31, version 2.2.2*

Love this

### 5/5 — Another brilliant effort from an esteemed developer!

*2025-02-28*

Just like Nussy’s other work, B100X champions itself as another great game amongst a sea of mobile games that are clones of one another with little to no innovation. Nussy’s collection proves that the developer is in tune with what makes a game fun and original. One can only hope that the gaming community collectively rallies around developers like these to support future work. 

Definitely for gamers who enjoy rogue like games, idle gaming, resource management, RPG’s, etc. Has its own charm that does not take long to find and persistently grows on you with its addictive gameplay loop.

### 5/5 — 神ゲー　放置ゲーなのに爽快感やばい

*2024-12-13, version 2.2.2*

個人的に放置ゲーは嫌いなのですが、
B100Xはプレイしていて
とても楽しくて爽快感がすごいです
╰(*´︶`*)╯♡

### 1/5 — Rubbish game

*2024-11-27, version 2.2.2*

Not much to do each dungeon keeps changing sometimes it’s easy most of the time the enemies are 10000% stronger than you so basically you can clear floor 1-300 no problem the next run you can’t even get to floor 60 without dying. and equipment drops are extremely weak floor 1 equipment is the same as what drops of floor 300 you have 5 hearts basically life points and it takes 24 hours to restore so basically you play for 2 minutes a day. This game needs a massive rework done but it will never happen devs made and extremely easy to make game then abandoned it relying on suckers who spend with out thinking extremely greedy people made this game.

### 5/5 — Pretty sweet game so far

*2024-10-10*

This developer is awesome so I’m sure the game will only get better

### 5/5 — Good

*2024-09-13, version 2.2.2*

It’s too bad these are not front and centre.
