This game was made in Klik & Play, a piece of 20-year old game development software that doesn't play nicely with 64-bit Windows. The easiest way to play the Klik & Play games on this site is through GLORIOUSTRAINWRECKS.EXE, since it features automatic Windows 3.1 emulation.

However, if this is the only game on this site you wish to play, I went to the trouble of making a 64-bit compatible version! You should be able to download this and run it on your computer. I feel obligated to warn you now that the game doesn't actually allow you to have sex with a pokemon.

I also personally feel you may be a little young to be investigating pokemon sex. Curiosity is fine, but if you are at an impressionable age, you may wish to seriously consider if a fetishistic view of brightly-coloured fictional cartoon animals could burden you in your adult life (others here may disagree; feel free to comment if you feel my opinion is out of line).
