I'm a fan of the SproutLands tileset. The other art also fit in well with the color palette and style.
Unless I was missing something, the game seemed setup that I could not defeat the first waves. I just had to impatiently watch and accept damage. It wasn't until about the 3rd day I could start making some interesting choices with how I was spending resources and where.
Also, when I had a row of acorn launchers, I noticed the acorns would disappear a split second after being launched and not reach the target. Some would make it and "Miss" or hit, but a majority just fizzled into nothing. I struggled with the controls a little bit, too.
Good work getting a high score table plugged in. I think with a focus on polish and QoL improvements, this could be a fun competitive tower defense game. Congrats!
