From a game design standpoint, it seems a bit incongruous to have the lucky gummies only appear in survival when you unlock the highest upgrade level. Once I started playing survival, I barely bothered with the upgrades, thus not bothered to read the texts for them. If you had made it so that you have to upgrade to the highest level for all the different gummy types for survival, it would have prevented me from wondering why all the other types were there in abundance and no lucky gummies. Or, you know, you could have made it so that on upgrade 3 or 4 there was maybe 1 lucky gummy per section and then increased the chance of them appearing like all the other gummies do, giving a reason to actually bother to upgrade everything.
Pretty sweet game, my only complaint is the music... which is pretty good, but instead of being a perfect loop it fades out and starts again! Either get a few more tracks for some variety or have the option to turn just the music off.
I agree with wib, it's an ok game but it needs something to make it great. After finishing one game, I don't really feel all that compelled to play through again. Perhaps if the blocks fell in lines rather than single blocks falling all over.
'tis a pretty awesome game, but some points about the UI confuse me. Why is it that you cannot click menu items to jump around? When grabbing inventory items to use them with the mouse, it makes sense to make the rest of the menu UI mouse accessible also.
