The 1.21 update is now live. Level tuning from previous versions has been restored and the toxic tile has been tamed. See Britt's earlier post for the details. We are working on further changes that we believe will address even more of our users comments and concerns.
More to come...

I redownloaded the game app and so far it is sufficiently like the original that I am happy. I am only on lever 4 so far with my first game so we will see how it goes at higher levels. Even with the old game I had problems, not sure they were app related. I use an older Iphone 3G and that may be my problem I have had the app crash at level 11 every time I get there. I plan on buying a new Ipad 3 next week so we will see how I do with the new hardware. Developers, thanks for all your attention regarding the last update. You got me back! Now where was that 5 star button again?

Nervously brought the latest update on board and have just finished level 15. Not a toxic tile in sight! Brilliant! With volume turned down I can almost totally ignore the blue tiles, annoying though they are and it is very close to playing the game I love prior to the update that put everyone's blood pressure up!
Thank you for listening. Even though it should be noted that there are many of us who would never download an app that had An in-game payment element. If Welder had had this from the start, I would have by passed it.
Now if you could just make those flashing blue tiles less annoying....
Just off to upgrade my stars for you.

I haven't had time to work into the bigger levels, but the game seems to of returned to normal and feels like the classic.

Also noticed a better score for the gig tiles. (except I still think the design of those tiles are terrible.

I'm happy with the quick response. Lets see how it goes, but I'm happier.

Just worked my way thru level 14, and no toxic tiles!!!!!!! Thank you, thank you, thank you for listening to us all. I know this has probably been a very trying week for the welder crew, but you came thru it respectfully and with a lot of class! I have my favorite pastime back! Thanks again. Keep up the good work

I will use fewer exclamation points than others here, but I would like a way to revert to the version before the recent update.

Perhaps I spoke too soon. At level 10 I had to deal with 4 toxic tiles, maybe 5, I lost count. the last one dropped onto the top line between two broken tiles with a hot tile underneath. Killed my game. All appeared with 10 or less swaps. I had another 4 toxic tiles between level 5 and 10 that I had to do away with, again at a time when I did not have that many swaps. Very frustrating, and that is not why I play W.E.L.D.E.R.

That is not supposed to happen. Can you email me at support@highlinegames.com?

Some way I did not get the new game when I downloaded the new 1.2.1
I was playing the last update which is still flawed.

That's potentially good news. I'll see what it is like now.
