The imbalance, even if it was due to, might've been said as "unexpecting how HUGELY the computers will ADVANCE in four years," that happens in finishing the final level of the area 3 (that is _required_ to get the ability to buy da "supa-dupa" train, has annoyed me very much. I warn of it, thus.

So, I got to the point of that level getting the Accelerator and the Military trains fully "pimped" with upgrades. The cargo of the Whateverite Gas friggin' blow up on the first downhill, unless the huge luck happens. Then they blow up on the beginning of going up the next hill!.. I even bought the whatchamacallit Ancient train, that is described like it's all about Balance. Fully pimped the balance, 3 points in the two other sections, same 'tragedy.

I'll try to not get too personal with the score, this is a review, after all.
1.5

OMG its the arrow keys!!!

I tried over and over and over to get up that second hill just by using the spacebar. Apparently THE ARROW KEYS MOVE THE TRAIN!!!! Game is much more playable now.

Tutorial, because it doesn't have one.

Hold down the up key to move forward, press space when the bar builds up for a boost.

Nice graphics on this game, not sure about the gameplay though.

Not good,

Graphics are ok but the game play is bad. I don't know if I picked the wrong train or what I cannot get past the 1st level. Nothing is explained very well either.

Short and not particularly satisfying.

First off, a tutorial would have been lovely, not to mention a mute button. Secondly the fact that all of the cargo seemed to be practically weightless destroyed an aspect of gameplay that could've made your game at least slightly more interesting. Varying the weights and maybe even making some heavy enough to counteract the train's bizarre tendency to crash its front into the ground when going downhill greatly would've added a little something (not to mention the fun times you could've had with varying gravities). Also, what's up with the last moon level? The fuel canisters or whatever they were seemed to go off randomly; going fast didn't set them off and neither did rough handling (separately, of course, together is obviously a different story).

I got gold on pretty much every level first try so there's really no replay value and certainly no incentive to buy the "master train" that was the reward for beating the game.

It's not all bad though, I did find myself sporadically enjoying the game. However, if you made it harder, less frustrating, and used actual real-life physics it'd probably be considerably more entertaining.
