Game speed over Time?

Hey Guys, I've hit a brick wall. Using the autorunner template I'm trying to create a fun lil autorunner that will increase speed gradually over time. I added this, which I thought would do the trick:

System - every: 5 seconds - tiledblock : bullet speed : "block.Bullet.Speed+20"

I thought that would work, but the problem seems to be that when the tiles are generated again, they return to their default values, so it will only speed up if the block is active for 5 seconds on screen, then it returns to -20 again when the new block is created.

hope that makes sense, I would really appreciate anybody's help on how to fix this.

Craete a global variable blockspeed and set it to the initial bullet speed.

System - every: 5 seconds - system : add 20 to blockspeed

                            block : set bullet speed to blockspeed

on block created - block : set bullet speed to blockspeed

LittleStain it seems so simple now!!! thx a lot littlestain!
