I don't understand the weapon upgrade system. Once you get the rocket launcher, there's no incentive to upgrade the other weapons. But upgrading the shotgun to the second tier costs way more than the rocket launcher.
This game is awesome, but it could really benefit from some small improvements. Sorting my units by various attributes would be great (species number, most notably). When I find new creatures, I want to know if I already have that species. And sorting quests by completed/uncompleted would be nice, as would a UI change if a side mission has been completed before.
There should be a bookmark all (and un-bookmark all) button for great weapon parts. When shopping, I often want to know if I have any great weapon designs that use that part.
"Look at that turtle!" says my penguin. *waddle waddle waddle MISS* "Ooooh! Look at that other turtle all the way across the map!" *waddle waddle waddle MISS* Repeat until dead.
So many things wrong with this game! The upgrade system is the annoying thing where you can skip upgrades if you do it right, so you always feel like you're wasting money if you're not buying the best upgrade. The AI can't move around walls, which makes me wonder... why put walls in the game at all??! The abilities don't have hotkeys, so it's nigh impossible to pick up money and help your penguins at the same time. Also, if you skip a penguin upgrade, it makes it look like you haven't purchased the previous upgrade, but at that point, why would you?! The more I played it, the more I hated it. 1/5
Levels need more variety. Limitations would be cool. Start with less money, restricted to building only certain kinds of buildings, etc. As it stands, it's the same level over and over, it just cuts you off at different days.
You can replace almost any major building with any other major building, except for the school. This is pretty frustrating, since you never need that many schools. Other than that, this is a great game! I can't wait to try it on the hardest difficulty!
