Hi!
Sorry to hear that it crashes.. It's also quite strange that it actually does manage to load to the startup animation. Maybe we can get to the bottom of this. Could you send me your log file? You can find it at: ~/. config/unity3d/Placeholder Gameworks/Death and Taxes/Player. log.
If you could send that to oak@deathandtaxesgame.com I would be very grateful and it may shed some light on why it crashes :)
