Why does wind tilt the rocket? The force is evenly applied along the side of the rocket, so there should be no torque. Also gravity remaining constant at all altitudes is wrong wrong wrong. I'm guessing air resistance has the same problem, but I can't really tell.
Those warthogs are unstoppable. Also I notice my exp carries over the same after each game over and retry, but I can't get any upgrades from the levels I supposedly gained.
The last few levels left me confused. The text led me to think that the last level was unwinnable and that I was supposed to start over, reach the flashback, and just not have the two meet. So I was rather annoyed to find that this wasn't the case and that I simply had to keep screwing with the last level until it was so flooded with ghosts that I could collide in midair and jump again. Repeated all the other levels for nothing...
The level 9 boss is pretty much broken. Most of the bullets are spaced together too closely - your ship can't squeeze through and so you can't avoid taking damage. I'm certain that A rank is impossible because of this.
I tried printing to PDF, the only option available to me on my laptop, but couldn't actually find an output file anywhere. So yeah, looks like that one requires some hardware.
And the wheel and candle aren't really any better. Sure, they're solvable in theory, but who's going to come up with those answers without checking the hints? I'm also stumped on green light, no clue what exactly I'm supposed to do with my mouse, I've tried clicking while green, moving while green, clicking and moving while green...
After a ton of refreshing, my zombie is now in a lurching pose next to the grave, blinking for no apparent reason. Methinks some bug fixing is in order.
