Thoroughly enjoyed the game, well-made animations, well presented and easy to pick up. Even though the defense options are limited there's fair bit of replay value to be had here even though the difficulty goes down if you know what's coming ahead of time from previous attempts.
The tl;dr of it...
What I liked:
- The simplicity, with emphasis of making quick decisions.
- Difficulty felt pretty balanced.
- Presentation
- Audio/Music is great
What I felt could be improved:
- Tankmen feel grossly underpowered especially towards the second half of the game when you start dealing with a lot of units which force them to sit idle and do nothing.
- I didn't notice the upgrade tab until half way through the game. Not a huge deal, its just easily missed.
- There is minimal visual indication as to what turrets have what upgrades, mouseover info would have been nice.
Either way, excellent work. It's been a while since I've played a fun tower defense game.
