I love this game to all hell I got the game after 20 friends and prob around 90% of the internet said it was the ebst game ever and being told to do it blind ok no problem after playing the game I loved all the charecter's, sans was my fav but I did a neutral run like 90% of people did, I blame every RPG the game was an easy level with no difficult part's. after sparing flowey(thanks to my friends warning) My reaction to the murcy part of the game made me happy I could spare awesome charecter's like pyrus and toriel but after reseting the game I found myself getting alot more frustrated due to the fact that figuring out some pattern's to spare some monster's was chalangeing, I found myself on some enemy's making blind choice's to try to get through the game(the cimera's in the true lab where the hardest for me), although I found the bosses easy to deal with another issue I have with the game is the difficulty spike at the end, I died so many time's on asgore and mettaton(omega flowey and asirel was not that bad though) but finishing them made me happy, like overcoming a great chalange the last issue I have with the game is the difficulty of the kickstarter credit's, holy s*** the amound of time's I failed the do not get hit part was a nightmare, I lost so many hour's of sleep trying to get the timing down for it, but like before finishing it made me incredably happy this game is great, the charecter's are memorable and loveable, the gameplay and mechanic's are amazing, but the difficulty spike at the end made me rage more than any game I have ever played before I give this game 9/10
The only boss I died on was Sans. And even then, that was 4 times. That's the only REAL difficulty in the game. The rest was real easy, and I didn't even know Temmie Armor existed until I started messing around with the Temmies and saved up for the shopkeeper to go and graduate. But yeah, it's a good game. It has its replay-ability, but only for so long. It's not a game you can sit down and play forever, mostly a game that you can relax with for a bit.
In the beginning I didn't want to play it because I felt like it was overhyped. Now I have 160 videos of it. The only problem is that I kind of started to dislike the game. The reason for this is because I finished it 26x and sort of sick of it. The thing I dislike the most about it is all the AU's, like Underfell, Underswap, Floweyfell, Dancetale, Inktale, Horrortale, etc. I think it should stick with the original game, and not the whole Underfell and Underswap things that the fandom created. Other than that, it is a great game with a lot of possiblities and great soundtracks.
