welcome then.
i cant find the game by searching on kong, can you provide a link for it ?

did you try using one of the tuts ?  https://konghack.com/view_topic_latest.php?t=3331

anyway, it sounds like you may have either picked the wrong process to use speedhack on or/and you set the speed too high


a sidenote:
i see you only have like 10 points, (thats enough for 5 days)
But i would strongly suggest you make a review, apply a hack etc etc.
else your account is going to be point dropped and you will have to wait around for a redemption mail :(
ill pop in 50 points for you and hope you will manage to get it up again :)

uhm...i think your post is in the wrong place, cuz the game you are posting in are NOT the same as the link you are providing.

ANYWAY.. the ball game is as you write in Unity that means (in firefox) you have to choose the 2nd plugin container process
and then set the speedhack as you like (about .5 will do the trick)
and it works no problem :)

I have also run into the problem of using speedhack crashing games. For me it turned out to be the 64 bit version of CheatEngine running on a 64 bit Windows desktop caused the problem.
Try using the 32 bit Cheat Engine option and see if that works instead.
 

I was meaning use the different Cheat Engine programs, but still choose the PlugIn Container once you have it running.
On a 64-bit machine it installs 2 different copies of Cheat Engine, one may work for speed hack for you.

I have that problem when I raise the speed too high as well. If you're using a very high speed try raising it slightly then work your way up from there to test the limits. That's how I learned my laptop's limits.
