This is one of the most underrated undertale games ever, and it needs more recognition because it's really good!! the game design is so creative, there's a bunch of cool dynamics of gameplay and characters to use, and probably more to come! I know the creator has been working hard to get new updates every few months. Overall an amazing game, amazing designs, dynamics and attacks, and can't wait for more!

Literally every feature of the game says it's "coming soon" except for the basic mode. I tried playing that but there was an annoying banner ad at the top of the screen the entire time. I honestly didn't know what I was supposed to be doing in the game. Right at the moment I either won or lost the first level a very loud obnoxious ad started playing and at that point I gave up. Does Toby Fox know that this cheap rip off of his game exists???

The game is great so far. Ever since character creation hot added, the game got more interesting, and now it has some crazy abilities along with some from the npcs. The issue with the game is the bugs with the shop and character creation. The shop is the same as always, sometimes it responds normally, and sometimes some items wont load properly. As for character creation, its gone back to the same issue where it wont save any changes you make, abilities or vessel.
