Overall very cool concept! There are some improvement that can be made on the art side but very cool idea.

There are still two things that annoyed me:

One is that i wasn't able to buy towers or click buttons sometimes... (those are just technical issues)

But more importantly i would make the map be more like a tower defense game map so everything is on One screen (no camera pan) and make the roads go over each other so one tower can shoot the same enemies twice.

interesting idea I think you were able to pulloff randomness in a way that avoids being annoying. the art could use a lot of work and there is various things you can do to help improve pixel art. I would look at this https://hackernoon.com/making-your-pixel-art-game-look-pixel-perfect-in-unity3d-... for more info. also look Into the pixel perfect camera its very important to getting your pixel art looking good. I was only able to play level 1 the game seemed to freeze at the beginning of level 2. great job getting this done in 2 days :)

A brilliant tower defense take on the game jam theme! I think if you had a bit more time, you would've been able to polish the game. The movement is jittery, and I recommend on experimenting a bit on Rigidbodies and Physics in Unity. Also the rotation of the tank isn't proper, but that doesn't ruin the overall experience. Great effort!

It's has a nice concept, but it can improve a lot more.
the art style is not that bad, but it's hard to see and is not so consistent
the music is not good nor bad, the sounds are too loud, try to export them with a lower volume.
The mechanics aren't so clear, but yet it could be better
This game is overall regular, but if you put more effort, you can make something that is more fun to play/experience.
Keep learning!
