Nope, not too bad at all. I actually spent a lot of time with that game. The best part of it was that the game didn't really tell you where to go or what to do. You kind of had to figure things out on your own. You got passwords every time you beat levels, so you wouldn't necessarily be sent too far back... The problem was though... When you first started playing it... you died a LOT. The first level consisted I think of the T-Rex Paddock as well as the Triceratops Pen next door. After that, you were in some Stegasaurus enclosure where they ate plants and slapped their tails against the cliff-sides.... which would drop random rocks all across your screen.
Each area had its own set of objectives and tricks, which made it kind of fun. You had to rescue the kids in the first area (finding Tim was easy once you knew your way around and could be done in the first minute of gameplay) and then getting to Lex was a bit trickier as the Sewers were full of what looked like T-Rex in the water which would kill you instantly if it touched you... You had to push a box to her location in the upper left of the map... But getting the box there and back was a nightmare if you didn't know the proper path... Once you got the kids, you unlocked the gate and left... Then, you hopped into the Triceratops pen and you had to pick up a crapload of flowers in order to get passed the Triceratops that was going to run you down at one section. If you had enough flowers, you'd throw them on the ground automatically and it would stop to eat them all... Well, more accurately... The more flowers you had, the longer it stopped. You had to have nearly all of them to get through the area, 'cause he was a fast eater and a fast mover.
The stegosaurs... I never figured out that area, I'd always die partway through it.
Still, most of the fun of the game was exploring and trying to figure out what to do and where to go, because the game didn't tell you anything.
