Once I figured out how to play it (skill issue, I've never really played a tower defense game before), I had a lot of fun with it!  I think the difficulty could actually be increased a little, because once you increase your gold a lot, there's pretty much no challenge anymore, but it's still fun.  I think the overall level design is good, but could be a little more diverse, but that could be a thing for future development.  Everything seemed to work as intended, and I didn't notice any bugs, so that's great!  An idea for the difficulty would be to limit the number of upgrades per level, and maybe gradually increase the speed of the enemies.  Also, different types of enemies might be fun, like enemies that attacked your towers (I don't know if that's something that tower defense games do...).  Other than that, I think it was great, and it's also a great foundation for further expansion!

I really liked everything about it!

The only thing I could recommend is more assets and more upgrade and tower options

The game functions great and looks really good as well.

Also it would be nice to clean up the UI to be easier to read as well as understand the instructions.

This game is really fun!

This was easily the most fun game I've played so far. I got so invested in the tower defense and upgrading felt rewarding. I might be biased just because I find tower defense games super fun. I didn't understand how the upgrade system worked at first, so maybe an indicator on the button when you're able to upgrade might guide players more. Another thing is that I wish you could delete/sell towers for a less than what they cost, because sometimes I would accidentally place down a tower somewhere and it would feel unforgiving to have it there forever. As a whole though, oh my gosh this was fun. I really hope you expand it! 

Lots of fond memories of playing Bloons Tower Defense 5 as a kid. Game is simple but very rewarding. It is also quite challenging, but the dev cheats in there are helpful just to make sure you can fully experience the game. It would be cool in the future to see full assets for the towers and enemies, but the core gameplay is great.

The game's UI looks good overall. I did not hear any music when playing the game. I enjoyed using the dev cheats to create an unstoppable force. The game does start to feel a bit repetitive, as the only new thing the game throws at you are the maps. Overall, I think its a solid game.

There is a problem when attempting to run your game, but it is an easy fix. The executable file is called "FieldsAndFeldspar_Corner", while the _Data does not share the same name, instead being titled "WardensOfDawn_Corner". Both of these files need to share the same name. I renamed the .exe and it ran properly.

It took me a second to figure out how the upgrades worked, so I lost on the first level in my first attempt. I thought that they would be on a tower-by-tower basis and did not expect them to be overall upgrades. Once I figured this out, it became so fun. Stacking gold mines to maximize gold output and then just upgrading everything proved to be a great strat, as I would get up to 1000 gold per second. 

I really like the main gameplay loop, but I wish there was a way to destroy towers that had been placed down, since I misclicked a few times in later levels. I also think there were a few instances in which costs didn't update. The gold mines stayed the same price to place throughout my playthrough, despite seeing they were supposed to go up in cost on the upgrade UI.

I liked the movement controls for placing towers it was really fun to think of our builder as an actually little guy producing these towers from nowhere. There were little things that can be improved like how enemies pile into the same spot to attack the base, which can make it hard to know how many there are. If you're using navmesh for the enemy pathing, I think you can make them both have collision. This would make them surround the base and be a better visual cue to the player that the enemies will keep attacking the base and not just de-spawn when they reach it The UI is also very wordy, if you continue development on it I think having icons for the different resources might make it more readable at a glance. Overall great game :D (Edit: I had to rename a folder to open the game, did you rename the main application but not the data folder?)
