Oh, man. So many hours of flash tower-defense games.
I had a lot of fun. Here are some things that, personally, I missed during gameplay:
- Soldier talking to us needs 1 more sprite while talking. Just an open mouth and slight different head position. No big deal.
- When you activate the extra speed button, player needs some feedback to know it is activated (for example, it could have a darker color, as if the button is pressed down). Also, since it has many arrows on it, I thought there were like 4 or 5 different speeds to pick from. Maybe 1 arrow when it's at 1x and 2 arrows when it's at 2x would be more intuitive?
- I suggest some terrain obstacles that force the player to time when summoning troops, in order to reach the enemy base. For example: Every 10 seconds an enemy bomber flies by, dropping bombs in a straight line. If our troops are walking that path in that precise moment they get in trouble. I also thought about tornadoes randomly roaming around, but it probably wouldn't fit the theme. I guess you get the idea.
