Pretty Solid overall, though playing in still silence is a little unnerving. A lot more math goes into this game than I'd expected and the management of buying upgrades as the game progresses on can be challenging and stressful.
Fun game, but some of the collision detection with falling on bodies is a little tough... There were numerous occasions where i SHOULD have fallen right on top of a previous spike + bouncy corpse, and i seemed to slide off the side onto the spikes... very frustrating when it happens.
You could have used some decent vector art for your maze instead of paint. Definitely try adding a few more levels with decent graphics next time around.
The game has virtually no improvement on the first. The asteroids moving across the screen were a nice touch, but they are in EVERY LEVEL. Also, there is no life system, so there is no sense of urgency in the game.
Some of the collisions are a bit buggy but not too bad overall. There needs to be some sort of loss though in the game otherwise the player has no desire to play nor feeling of accomplishment.
Controls are way too sensitive for the physics of the truck, tweak them a bit and the game will be playable... also, the 2nd hill is nearly impossible to scale with the extra nub of rock at the top of it.
