I've never heard of it, but if it came pre-installed you probably can't uninstall it without "rooting" the phone. However, on Android 4 you should be able to disable it - go to Settings > Apps > All, select Tapsnake and click on "disable". It will disappear from your app drawer and cannot be run unless you re-enable it. I'd "clear data" before disabling as well.
As pre-installed apps live in a different bit of the phone's storage from user-installed ones, uninstalling it wouldn't give you more space, so disabling it should be pretty much the same as uninstalling in practice.
