This game is so cool and easy to play and yet challenging. Hits the spot! ### 5/5 — Fantastic fun *2021-03-18, version 1.0.1* Loved this game. Tough but generous checkpoints. You might die 20 times in a single room until you perfect the precise platforming. But remains fun at every death. Reminds me of Celeste plus an exploration component. Bravo! ### 5/5 — WOW! *2021-02-26, version 1.0.1* This game is simply awesome. Wish it had no end, just keeps you engaged and occupied. Spent hours playing and not getting bored. Kudos to the developers. This game must, must, must have a sequel. ### 5/5 — Legitimately a great Platformer *2020-03-04, version 1.0.1* Like you I was maybe a little put off by the small number of reviews. But I took a chance and I’m really but I did because... incredible! Just got to say Great soundtrack as well. I’ve played a lot of platformers on and off iOS, so take my word for it you won’t be disappointed. ### 1/5 — Suddenly unplayable *2019-12-23, version 1.0.1* A bit into the game after unlocking some abilities, the game difficulty suddenly increases to a practically unplayable level. I am stuck on a level with no way to progress or go back and I have no choice but to uninstall. DO NOT BUY if you’re looking for more than 30-45 minutes of gameplay! **Developer response:** Hi there! Sorry for the bad experience that you had in Necrosphere, Necrosphere is hard-core metrovania-like game which challenge the player to get back to where they can not passed before after they got a new ability.The game had been testing by our hard-core QA team millions of time so we can promise you that the game is 100% playable : ) Based on what you said, seems like you are stuck on somewhere in the game and couldn't find a way to keep going, would you like to tell us where exactly you were stuck? We are more than happy to help you how to figure it out : ) And btw, we are currently making an official walk though on Doublethink Games' official youtube channel, and it will be released soon! Thank you and Merry Christmas! Team Doublethink ### 5/5 — Challenging and fun! *2019-12-08, version 1.0.1* It is hard enough that you get somehow frustrated but willing to try again. I am having a lot of fun. ### 5/5 — 👍👍👍👍👍👍 *2019-12-05, version 1.0.1* Challenging difficulty continuously is the pure joy of games. The maps, equipments are really creative and delicate. In this game, you can feel the beautiful pixel art devs provide, absolutely Necrosphere is a game deserves more awards and recognization in my mind. I’m expecting about this now.😍😍😍 ### 5/5 — Best Platformer Game For Mobile!!! *2019-12-05, version 1.0.1* I am a huge fun of Platformer games since I was a child! Have been searching for an interesting Platformer game on mobile for years, and Necrosphere is the one! There are no complicated control in that game, you only need 2 buttons to control it but it doesn’t mean it’s not challenging at all! Tons of the fun mechanic and trap and I am sure you will enjoy that : ) ### 5/5 — Time Killa machine *2019-12-05, version 1.0.1* Game might be a lil bit hard, but I love challenge. Really cool game for time killers. It makes a great company with those lofi radio I’ve been listening to ## Frequently asked questions about Necrosphere ### What is Necrosphere?
