It's actually enjoyable!

The characters are likeable, including Boxxo (the vending machine MC); he doesn't "speak" per se, but you got access to his thoughts and he does communicate with other characters through a simple ad hoc code (using his stock phrases, like "You might win an extra item!" to warn about enemies, or "hello!" / "too bad" for yes/no). He has lots of abilities but the fact that he cannot move by himself prevents him from being overpowered, plus he needs cooperation from the other chars but with his limited communication this is often hard.

So it's no AOTY but it's that sort of stuff that you don't mind watching just for fun factor.
