This is a nice little tower defense game. It seemed like there were some interesting ideas in it but I had a lot of trouble figuring out what exactly was going on beyond the most basic tower building mechanic. Even that took quite a while to work out since the first thing I clicked on was a weapon which was useless without a tower to put it on and I had to back out of the game and look at the instructions again to figure out that the space bar would deselect it. I would expect clicking on the tower builder button to deselect the weapon if I have it selected.

It was unclear to me what the dice rolling mechanic did. Did it effect all towers? Only the selected one? Was it temporary? Since I couldn't see the stats for any individual tower it was hard to tell.

I also couldn't work out what was different about the different colors of tower. Maybe the more expensive ones did more damage?

Definitely would have benefitted from a simple tutorial. Cool idea to have towers + weapons as upgrades!

As others have said, I found it a bit overwhelming at first. But I'm impressed with the amount of content you had!

Game bugged on one of my failed attempts and round counter kept going up and up, went beyond 3000 rounds and many thousands of gold/currency before I closed it.  Then I got sad because I had to close the game and lose my progress :D (

Fun game although a tiny bit confusing at times, like I had to play a while to get a feel for what the different towers and different staves would do as a powerup. Didn't figure out what all the other weapons did except the axe.  Other confusing moments was the pause button as others have mentioned, and the selection/deselection mechanic. Discovered the main feature of dice rolling towers a little too late.

I thought the colored "towers" had different abilities at first, such as blue = slow, green = aoe and such, but I assume they are just different stats version of the same tower.

I was building an idea that the strongest possible upgrade for a tower was to make a red tower with red staff for max damage, then upgrade it max with speed since each 0.1 second would weigh the heaviest vs ~0.15 damage.   Or in reverse; the fastest blue tower with the blue (or yellow staff) with max damage upgrades would make the machine gun effect hit the hardest.  Red with axe was a fun shotgun up close effect.

Your game has lots of potential! Keep it up :)

A possible direction to take the game is to go into the main mechanic more, mainly the dice roll.   For a chancy game, I'd think if you could balance the income with a no-upgrade-limit, it would make a stronger dicey experience. With increasing cost it will balance itself out, and getting better dice rolls through upgrades between games might give it a sense of progression that carries on between games, like a rogue-lite would make you a little stronger game for game (like Dead Cells).   Something like Warcraft 3's custom game Poker TD comes to mind. Luck is a major factor but your knowledge of the game matters as well

The core gameplay is great, I think it's a good tower defense game. However, it really lacks a lot of quality of life stuffs, like a tutorial, a better control scheme (as you can see below, several people got confused on space for deselect unit), visual indicators for the range of attacks, enemies health bar, and some clear guide on what does each type of towers does. 

Once one of my towers was selected I couldn’t select any other unless I sell the selected one

Also, the effect of the dice wasn’t obvious, maybe if it had a bigger effect or the color of the enemy change as it get a modifier that might have drawn a bigger attention to the dice mechanic

Cool game! I clicked on it because it reminded me of Dicey Dungeons and I loved that game. The gameplay was fun but I was a bit lost at first when I was just thrown into it without a tutorial, so if you are planning on continuing working on the game I'd suggest adding that. The dice idea for a tower defense game is really cool, I just like adding dice to anything in general. Enemies stopped arriving at wave 11, I'm not sure if it's because I won or if the game stopped working. I'll still count it as a win in my books :)
