Nice game!

Some random feedback

I feel that UI elements could be a bit bigger. The about button doesnt work

I first did not realize what I should do :D Like I had the bucket selected and needed to figure out to switch to the finger mode.. maybe some simple arrow with text would help. And then when the first batch of bugs is smashed another arrow would point to the field - first I did not get that I gotta go there. Although after ~3 minutes I could understand the game loop. Perhaps, the only confusing thing was the bug colors/why sometimes bucket doesn't collect bugs even though it has space.. like what's the big difference between them :) 

One minor thing, maybe you should preload animation/models/whatever. In web, when I crushed the first bug it froze a bit

The game has really nice graphics actually. I like the models, the colors, how the crate shakes when hit. That looks really solid!

What I would expect as the next upgrades:

• Maybe choosing (or getting) new plant types and hence getting new enemies so it has more variance
• More upgrades, more diverse ones.. maybe some auto-smashing upgrades if you lean into idle. Or some upgrades for, dunno, finger speed, area of effect etc :)
