I doubt Smear-Gel is using 2.3.5, his smartphone shipped with 4.2

Hope the update fixes the problem, it would be horrible if your game got some bad reviews because of it not working.

IMO, you shouldn't have made such a graphics-intensive splash screen if the game itself uses simple graphics.

The splash screen shouldn't really be all that intensive. The problem (I believe) stems from the way some phones send touch events to the game. On the programming side, you can interpret touches as a touch or as a keyboard event. In the start screen case, it checks for keyboard input, but in pretty much all other cases in the game it checks for touches. On all devices I have ever tested (both Android and iOS), I have never seen this problem. This is also why I'm not 100% sure the fix I added will work, because I'm not really 100% sure what the problem is, I'm only guess. Assuming the particles aren't lagging around, it is my guess it isn't the graphics, but instead the input. Also, the graphics may be simple, but the game is still pretty CPU intensive, with a lot of enemies moving/dying/spawning, along with bullets flying and whatnot, so the start screen still isn't the most intensive part.

I'll give it a go :)

The update should be up and live. Let me know if this fixes the tap not working. Thanks!

Nope, sorry. :(  I'm also sorry if you felt pressured for a quick fix because of what I said ("it would be horriible" etc), that was tactless of me.

The intro is beautiful, at least. :p

Gonna keep my eye on this thread so I know when the ios release comes out I'll try and download it day one if possible.

Interesting. When the issue if fixed I'll give it a try. :)

When you start up the game can you make sure it says v1.1.1 at the bottom right, just to make sure you have the newest version. I'll continue looking into it, I'm trying to find someone with that phone so I can test it, it's just so weird I've never seen that problem and none of my testers has that problem so it's hard to replicate and fix :(

The iOS version should be out later this week... Apple takes forever to approve apps so I can't release it until they do (I submitted it over a week ago and it's still "waiting for review" lol).

Edit: And no need to apologize! 

Yeah no. My phone is  4.2. Will still check back here after a while though

I was able to get my hands on a Samsung Galaxy S running 2.3 and it seems the problem actually lies in the sound system. I use a plugin called FMOD for some sound effects and whatnot (makes managing sounds easier as well, compared to Unity's default sound system). Unfortunately it doesn't seem to load correctly on 4.2 and under for some reason. I tried a few things to "fix" it, and by that I mean make it so the sound system isn't accessed if it doesn't load correctly (so that you could still play, but without sound), but the system is too intertwined into the game to just be able to not access it. The newest release I'm putting up (which has some other minor bug fixes and internal changes) will increase the minimum Android version required to 4.4 (Kit Kat), as that seems to be the lowest version that the game works.

I apologize to anyone who wanted to try it out but doesn't have the version high enough required. I am really disappointed this was never discovered during testing, specially back in early development, when steps could have been taken to ensure it worked on the lower Android versions. Alas, that is the downside to small time development, we don't have the resources to check every device and version (and since my teammates and friends are all pretty tech-savy, we all have the newest versions of everything, making finding a device that runs a lower version harder).

The iOS version is still pending, so I will post again once that is ready to go. Thanks for all your support and feedback, feel free to continue commenting and I will reply as soon as I can!
