Nice game, but i can give only 3/5.
After a while, even before complete all main waves, it is a bit boring and easy.
So little upgrades and they are so much expensive. There is no need to add more weapons, i like this game, just add more devastating upgrades to rifle, like a beam, pacificator, like old astroships games where weapong just shot in the same time.
You can change a little bit more upgrade's graphic, and add few more sky drops, like bonus damage, more money, i don't know.
It's a great game, but there are a lot of great games with potential left abandoned.
Nice game, but kinda boring after a while.
BUT i loved the idea that you can switch aliens' weapons.
- More weapons
- More mods
- More upgrades (stats? wall's upgrades? more R3D3 style things?)
i'm saying banal things, but i'm not a game desiner! :)
3/5 for me, but it can be without problems a 5/5 with few things more.
