The graphics are no where near good, not even for the 2600. Your Kangaroo looks sort of like a Kangaroo... or maybe a rabbit. I think I would have been completely confused had this game not been named "Kangaroo" about what I was. If you duck, suddenly your rabbit looks like a completely different rabbit -- this one made out of plywood or something. The enemy monkeys look more like spiders. The levels have fruit which you can grab for points, that look horrendous. In fact, the only thing that this game has going for it graphically is the nice looking bell that is on every level. Pretty sad for a 2600 game released in 1983.
The sounds aren't that great either. The hopping of your rabbit.. erm, Kangaroo sounds enjoyable for about five seconds. The sounds of you hopping and punching also get old very quickly. When you hit the bell, an annoying song plays. Again, this is quite disappointing for a game that was released in 1983.
The control is actually not that good. I usually give 2600 games a control rating of 90-95% because there just isn't much that you can screw up with a four-way joystick and a single button, but Kangaroo manages to somehow screw it up. If you fall off a platform of any height, you are dead. Adding to this, your jumps take forever to do, and often times you have to plan when to jump in advance to miss whatever the spiders... or monkeys, or whatever are throwing at you. It is not an enjoyable game to control.
At the end of the day though, I am still attracted to this game for some
reason. I want to make sure that momma makes it to the top to save her
baby. There is something oddly enjoyable about this title that makes me
keep coming back to it, so regardless of the fact that it has poor
graphics, sound and control, it is going to get a decent rating. If you
can find it cheaply -- and I'm sure you can -- it might be worth trying
