Hey bro..All good, is tricky and it helps to yell out as others will work out what to do as well. In every Stage you have a chance to grab an Item. So in Stage One you grabbed one level0 using luckydip and you paid 0.01 - so all good.
In stage two you paid 0.02 then used luckydip, which means your 0.01 in the credit.

The good news is you have now won both Stages and may upgrade to Level1.For fun you can type !upgrade1 in a reply below at end of you replies if want to..so yeah, starting next Stage just pop a reminder you have taken the helmet +2. It's permanent and will stay with you for all Stages now.. Only issue is level1 items cost 0.02...so you just need to transfer another 0.01 and your all done :)
