You Should Unlock Seeds after beating a level.

first let me state, I believe that unlocking fusions with seeds is completely justified. Base plants should be unlocked from levels. But it’s really hard to unlock fusions, so I suggest after beating a level you unlock seed packets of two plants (cause it’s PVZ Fusion) it doesn’t have to be much, even two seed packets would help. But unlocking seed packets for beating levels would be a great way of unlocking fusions without having you take 8 months just to unlock the plants from this build.
