Yep, that wasn't intentional, was a bug where if you pressed 'Q' and you weren't on top of a plant, it would simply destroy the first plant you came to. Have fixed that up, and have sped up the spawning process in the latest versions to keep things moving. Will upload it once the voting is over.
Also was planning to add in some mechanics like watering to keep the flowers from dying and a few other ideas to keep it more interesting, but didn't get time in the jam, so I'll be adding all these in later versions.
Will be sure to check out your game.
