I loved it! Although I don't play tower defense at all.
I avoided the game description on the itch page and started the game without it.
First I learned how to put up towers, and then I learned how upgrade them with a random click :D
A cell highlight when hovering would have been very helpful, so the player could immediately understand the interactivity of clicking without needing to click.
Also, maybe you know, the cells at the top and the cells in the top right corner are hard enough to interact. The pop-up menu is covered by the edge of the screen. And in the corner, the pause and speed up buttons also overlap the purchase/upgrade menu.
Every level I felt that I was on the edge of defeat and could lose, but I managed to beat all the waves. Very pleasant feeling, and a lot of defeated dice, giving me coins, multiplied the pleasant feelings :D
Sometimes I didn't understand which turret was going to fire at which location. And it was a bit odd when turrets covering 2 roads would fire at those dice closer to the turret, rather than those closer to the end of the road (and the potential damage to the main tower).
But other than that, it was an enjoyable game!
