I've also suffered from a major bug: all my offices vanished and I have now my workers standing there... And I read there is no save function???
Gosh, I will revise my ranking!
1. When picking up a new weapon, it switches to this one automatically. It would be better to switch to the most powerful one or to not swith at all.
2. It's sometimes hard to see all enemies.
3. A list of all the powerups with their in-game apects would be nice.
4. When being defeated, the possibility to re-start the same wave would also be nice.
To me, the fire ball seems to be the most efficient whatever the level...
Given you have to select one super ball and cannot switch is bothersome... The reload time associated to the ball you select does not impact much your combo-meter has you generally have to find the correct direction to aim...
OK, where do you track your progress?
There is no reference to see which levels you've already beaten.
BTW, I've been through levels 1 to 10 in the human campaign and I don't have the medal...
The blocks' shaking leads to a huge loss of time, making this game unnecessarily hard.
Plus it's a bejeweled-like game, you need to add a specific feature.
3/5
A bit too easy... Didn't have time to purchase big guns/turrets before completing the balloon repairwork...
Needs different sets of difficulty, a survival mode, or the possibility for creatures to damage your forts while you hide/sleep up there.
