I like the changes since I last played. The circle showing tower range is nice. The tutorial having 2 options and clearly saying how to end it is helpful.
When trying to change settings, I found that I could only click on the left half of the words for Full-Screen and Stretch Screen. The setting did have hover effects, so I was able tell where to click when I moved the mouse around after it did not work. I initially clicked on the checkbox.
Level 3 felt like a significant jump in difficulty. I had to redo it many times to find a strategy that could win, and still lost some HP. I found this one to be the most difficult for me, and took the most tries to beat. I think you introduced too many things there. You had enemies from 2 directions, armored enemies, and fast enemies.
Armor damaging towers should favor targeting armored opponents. It was frustrating how often the armored enemies pass by untouched by those they could destroy armor, yet being hit by towers that could not damage them. Similarly, for level 8 the start and end being so close had many towers hitting newly entered enemies, when the priority there should be the ones closer to the end. It was hard to position towers well to both get their maximum range/effectiveness, but also have them focus on the lead enemies that were the greatest threat at the time. Maybe move the starting path up 1 tile, so the tower placed on the bottom tile will have more time to focus on the enemies close to the end. Iām sure this challenge was meant to be part of the design, but the way the towers target enemies made it more frustrating, than a fun challenge.
Level 6 felt far too easy, especially compared to the difficulty of level 3. I often had a lot of currency sitting around as I decided what might be worth adding.
It would be nice to know how much each upgrade was going to cost. I only did the basic tutorial, and forgot that upgrades were in the game, so didnāt even look at them until around level 7 or 8. Even then, I did not use them much.
The fire tower numbers do not change when upgrading.
Overall, this felt like a nice set of improvements. The game is progressing well.
