The game and watch version of this was the first video game I ever owned. I loved the simple loop and that combined with the speed increase as you beat levels turns it into a hypnotic rhythm game. I completed the G&W version by getting the score to reset to 0 when I went over the max possible score.
Honestly pretty good and deserves more credit! The mechanic where you're faster climbing up when using a hand on two separate vines but faster climbing down with both hands on one vine is really neat. The four levels aren't all that interesting and it is shockingly easy for an old arcade game though.
