My first full playthrough of this game was on the hardest difficulty! It was extremely rewarding and hard af! This game is amazing and will always be remembered as one of the best story driven games I have ever played. I would even say it is better than Undertale in the story in some ways. Of course, the game is graphic af with the gore and the storyline and how it all takes place. I would say to start off play Undertale first, LISA second. You will not regret it. Undertale has a very interesting story that isn't very intense till you get toward the end. This game ups the anti 10x or even 100x more than Undertale. It's like playing a kids game to a teenagers game, to playing a completely rated M psychos dream game. I won't talk about endings in this review, but Undertale had a kids story ending..LISA..LISA puts you on your ass and destroys all that you have learned and literally gives you the middle finger while you play. Especially on hard mode... xD If you die in hard mode then you have to restart at your last save point. Your save points do not stay around. Until you beat a boss, two bosses, or three and specific enemies and then progress through the game you will have pretty much in some cases only one save for 5 bosses.(Depending) For example, I would beat 4 bosses and then die on the 5th where I would hope a save would be afterward, but when and if I died on the fifth boss then I would have to fight the four before him again. That is how serious this game is on hard mode. Buy this game, have fun, and stay dedicated! :) It will all be worth it.
