UNDERTALE is the perfect game in many ways. You have the choice of being a good guy or being a jerk by sparing or killing your enemies, and get different endings for both. Some people got turned off by the game because they got a bad ending, but that's only because they screwed up. If I wanted to be harsh on UNDERTALE, then I would say that maybe their a little too evil to you if you kill everyone, but that's kin of the point. The game play itself is good, combining 2D Bullet Hell and RPG's. You control a little heart in battle, and you can turn this heart into different colors, which change the function. Red is free movement, Blue is platformer/gravity, green gives you a shield that you can move arould the heart but you can't move the heart, yellow is like red but you can shoot little pellets, and purple makes you travel on three horizontal lines. The best of all is the story, but I don't want to spoil that because the story is basically everything, but I hope that's all I need to say to convince you.
