I just bought Mortal Blitz thanks to your recommendations.
I haven't seen any comments about Special Delivery, so I thought I'd post some impressions here. One look at the game will tell you all you need to know, really. It's essentially Paperboy VR, and that alone sold me on it. Deliver papers, avoid obstacles, don't get hit by cars, etc.
There are two things I recommend: 1) Play the training level. It does a good job explaining how things work. 2) Go into the options and speed up the turning, but not too much. Maybe about 1/4 of the way. In order to turn in Special Delivery, you simply tilt your body (head) left or right. The game starts it out on the lowest setting, making it really difficult to avoid obstacles, dogs, cars, etc. Turning it up will make your life much easier.
Overall, it's a fun little game, despite the fact that there's not a ton of variety and that you advance very slowly. The first few times through your route will feel very similar. Once you pass that, you'll have the additional task of collecting subscription money and beating a paper boy from a competing newspaper. Eventually, your route expands.
Cars seem to come from out of nowhere sometimes. Brake hard at all intersections! Those cars are unforgiving!
Worth $10? Sure, I think so.

In other news, I picked up Tethered on sale for $10. Great price for a really cool game.
