Otherwise, I love the game! Very fun, original, and unique. ### 2/5 — Last level just repeats *2020-08-20* Great concept. But no boss on last level. Felt like the last 30 didn’t lead up to anything big. No boss Previous levels were awesome. Really annoyed I keep repeating the last level with nothing happening when you beat it. Just an infinite loop. ### 4/5 — Level 150??? *2019-12-02* Great game but when are you going to make more levels after 150?? I’ve beat that level 9 times! **Developer response:** Please update to our latest version, which has 330 levels. If you have any problem, please feel free to tell us.our email address is nightkiller@boooea.com ### 1/5 — This is so bad *2019-11-26* Like it said not to get spotted but I can’t do anything your game is complete crap do not download 😡 **Developer response:** Thanks for your feedback, please update to our latest version. Thank you very much! ### 1/5 — Psh update your game *2019-11-26* How you gonna put out a game that you can’t even get past the first tutorial level **Developer response:** Thanks for your feedback, please update to our latest version. Thank you very much! ### 5/5 — Won’t let me play *2019-11-25* Says don’t let them see you and won’t let me do anything more 😔 **Developer response:** Thanks for your feedback, please update to our latest version. Thank you very much! ### 4/5 — Great Game- bit confused *2019-11-24, version 0.4.1* So when I got this I immediately loved it,I played up until level nine and then it would say victory and give me the coins but not let me go on to level 10.Ive tried this a dozen times and it still says level 9,Am I missing something here? I just turned it on and off and it fixed,Thank You ### 4/5 — Great solid game! **EDITED REVIEW** Level 90 fixed *2019-11-19, version 0.3.9* I was really enjoying the game until I hit level 90. This level appears not to have been play tested unless I'm missing something. Whichever trap door/teleport you choose to go through transports you to a dead end room with no way out so progression is impossible past this point. A decent enough simple game up to that point. **EDIT** Developer has fixed level 90 and added some new features so disregard the above. Great game that has a developer that actually listens to feedback AND takes action. 👍 ## Frequently asked questions about Night Killer X ### What is Night Killer X?
