I'm not sure the "Lemon Duplication" works. I've tested by buying it after my combo is maxed out in the garden and seen my gains not change visually, nor on direct-clicks, even as it's supposed to be increasing.
Also, the Tech Store in late-game levels is a massive frame-rate lag. The Particle Settings needs to also account for the item-fragments, they're the major source of lag. Hitting a boom causes a section-long freeze.

Yup, it seems like i messed up with lemon duplication, will get fixed.
For the performance issues, it's more likely that the performance issues are not from graphics but from all the calculations when something is being smashed, atleast it looks like it when im testing, though it might be different on the web version. The Steam version is coming very soon, I'm just waiting for the build review. If the problem persists on Steam, I'll look into it deeper.
