But everything that made it good has been removed. There are no more vibrations for shooting stuff The skins now all look like garbage -plus I can’t even change my skin for some reason The vibrations were the soul of the game but now not only are they removed but everything remotely good about the game was removed or replaced with something not as good. Probably the only thing that’s better than the previous version is that the health counter was lowered from 5 to 3 ### 1/5 — I’m confused *2020-10-18, version 1.20* I downloaded this game thinking it would actaully be pretty fun from the video but when I fully loaded in to the game all I saw was a black screen with a blue rectangle and 2 white triangles. This kinda creeped me out. I’m not lying. ### 1/5 — Don't bother too many adds *2020-08-05, version 1.14* One 15 second level, one long advert, can't be bothered, there are better ways to use your advertising, ### 1/5 — You killed the game with updates *2020-05-30* It’s actually sad on how good the game used to be. But everything that made it good has been removed. There are no more vibrations for shooting stuff The skins now all look like garbage -plus I can’t even change my skin for some reason The vibrations were the soul of the game but now not only are they removed but everything remotely good about the game was removed or replaced with something not as good. Probably the only thing that’s better than the previous version is that the health counter was lowered from 5 to 3 ### 3/5 — Fun Game Overall, Has Bugs *2020-01-29, version 1.05* It’s a fun game but I ran into a bug where the beam at the end of the level is missing and I can’t finish the level and progress further. Very frustrating, please fix this. ### 5/5 — Actually good *2020-01-24, version 1.04* It’s like the devs took more than two minutes to code this unlike half the mobile games out there ### 5/5 — Vibrate *2020-01-24, version 1.04* Option to Disable it ### 1/5 — Repetitive *2020-01-01, version 1.03* It’s a Shem because this game has so much potential yet is so repetitive, there’s nothing to work towards or nothing to unlock. ### 5/5 — Very good *2019-12-23, version 1.03* The game is nice but the one thing that bothers me is that the controls take to long to move side to side. So I you can go a bit faster would be better! ### 2/5 — Boring *2019-12-19, version 1.02* 5 minutes into playing this same for the first time I’m now deleting this game purely because it’s became very repetitive ## Frequently asked questions about Radiation Runner ### What is Radiation Runner?
