As an actual game, there’s really not a whole lot to unpack here. It’s an extremely simple VN game with reused assets from its predecessors (par for the course for LoK games, developers have been doing this for years), and nothing else to it. Pluto was at least honest about his work and didn’t try to paint this as anything other than being done for fun.
The animation was decent though little in quantity with lots of repeats, the corruption of Krystal was as basic as it can be, and the dialogue and story was readable and cohesive but too simple. The hook about the lust demon was dropped as quickly as she appeared and that disappointed me a little. There was an attempt to flesh out some characters like the female sharpclaws, though they sort of blended together in the end once Krystal slutted up. The lack of a proper ending is also pretty lame, after max corruption, further dialogue repeats and nothing else is there to be done.
For what It’s worth, it is at least said to be finished. Which is more than others can say for all other games that uses the moniker of The Legend of Krystal and is probably the first for its kind. So congrats man, you did it. You beat the curse by a technicality. Now watch out for those nintendo ninjas
