The concept does seem solid, but the balancing and bugs really affected the experience to me.

On my first try I couldn't understand why the acorns would take so long to shoot and even then sometimes they'd just disappear with no explanation, specially after the second or third day. I also didn't get why birds seemed to have such a longer cooldown on them if they were 4x as expensive, they just didn't seem to make quite a difference at first. Most enemies got through me pretty easily and I lost on day 4.

Then, on my second try, I understood I had to place the first few shooters more strategically and then put a giant amount of them around to make enough damage and have an overflow of acorns in my balance. Then I put some of the things that slow down the enemies around and, lastly, spammed the arena with birds. From there, it seemed like there was no challenge at all, I got to day 9 but it felt really pointless to go much farther than 5 (and there being no fast-forward button also made it slightly more tedious).

Overall though, the art is pretty good and, other than bugfixes, the main thing I guess the game could benefit from is just more work on general polishing and game feel, like showing a health bar for the enemies, sound effects etc. I may be biased for not playing a lot of games of this genre, but I sincerely felt it ended up lacking fun, mostly because of the stuff I mentioned. Still though, congrats on submitting, the skeleton is definitely there and I hope the feedback does help you improve it in any way!

This was a lot of fun! I definitely spent a good chunk of time playing. I actually have it running in another tab as I'm writing this! Hoping to snag the high score. 

I loved the animal sprites!

One issue I had was that a couple enemies would always show up just before dawn and there wouldn't be enough time for them to be destroyed. So they would run freely in the daytime and make it all the way to the Great Tree, despite the immense  array of defenses I had in place.

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!

I liked the art and once I figured out to really lean into the squirrels, I did well but ultimately had to give up due to the tanked frame rate.  I had lots of clicking issues where I couldn't select towers to upgrade, only initially place them.   I wanted to just keep clicking to place, instead of re-clicking the tower type.  Still, it was pretty fun, nice work!
