Really cool game ! Stressfull in a good way.
The gameplay is simple to understand & to get into. And the tutorial is really well made.
The music & sound a really on point.
In term of feedbacks, There's a lot of unecessary clicks and back & forth movements (really straining with a trackpad ^^). I kinda feel like the "place down" action could be replace by a double click or a right click instead of a button in the corner of the screen and the rotate button by a scroll. I also don't really understand the need to click on a truck before placing your piece . The grid seems already big enough to aim properly & the send truck button could be displayed on top of each truck. The whole interface seems a lot more appropriate for a touch screen than for a mouse input. If that was indeed your intention & this is more of a mobile game it could ba a good idea to recommend playing on phone on your page. :)
The game over is a bit sudden and send you back to the menu pretty fast. Giving a few seconds to the player to realize he lost and be able to see his score would be a good idea. Also Displaying a high score somewhere can be a good incentive to keep playing & beat your own score.
Tiny feedback on the tutorial also. the button on the middle of the screen could be replace by a click anywhere on the screen (but that's really nitpicking at this point)
All in all. It's a pretty fun game & really polished for a jam game. With a little rework of the UI & controls to reduce the number of clicks, you have a really cool game here. Great work ! :)
