Crayon Physics Deluxe silently closes on startup after showing the Kloonigames logo on my Nexus 7. Runs fine on my Galaxy Nexus, however. A shame, would love to play this on a tablet.
I am having the same issue with Waking Mars, sent a mail to the developer. I hope they fix it, the trailer looks amazing.
I get the same crash/shutdown experience, but with the Galaxy Nexus. My Nexus is running 4.0.4.
Hang tight -- we're working on an update for this. This is the first time these games have appeared on Android and we're still ironing out some device-specific driver bugs.
Actually, while the silent crash happened to me too on my Nexus 7 with Crayon Physics Deluxe (I have cyanogenmod 10 rom), I tried restarting the device, then the game loaded fine.
