Playing solo is pretty tough, but you can beat enemies if you try. Plus, against enemies with high rebirths, even if you're playing with friends you still have to dodge on your own which can be kinda hard, and you can't just rely on friends for everything so you have to work at it, which is good even if people think 'just dodging all the time is boring, but maybe I shouldn't say that...'
Also, even if you don't spend real money, you can sometimes get certain skills and weapons gifted from friends and stuff, which is another nice thing.

The downsides are that updates are pretty rare, and since there are strong event items and stuff, there's a gap in strength between veterans and new players.

Because there are so many secrets and completionist elements

As it says at the start, it's basically an RPG where you progress by fighting tough battles and increasing your level and resets. First off, you get to experience that unique undertale world. You can have dream battles with tons of enemies like sans, papyrus, undyen, and more. Not only that, but you can enjoy undertale AU and even the world of deltarune in the latest version. Maybe you can even fight those tough bosses from deltarune...? It's generally beginner-friendly, but even pro players can enjoy it, so I totally recommend it if you're bored or like undertale! You should definitely play it!

These totals come from players describing their own play. What players say goes up once our team has checked it.
