What real reviews say
★★★ Good but Impossible I am a big Roguelike player. I play every one I can get my hands on, to at least try it out. I actually REALLY enjoy/like this game. It’s a great Roguelike/Roguelite. HOWEVER (& this is a MAJOR deal), I am STUCK. Once I reached regular Level 10 & Elite Level 5-6…? The game becomes P2W, & is just IMP
★★★★ Potential to be great This game is very much so P2W and expensive if you do plan on spending money. Still a fun game though.
★ Do not spend money. The current events are primarily just cash shops dressed up as events. They are literally pay cash to roll dice and see if you get something useful. No gameplay whatsoever.
