Love that game. But Achievements are far too easy to reach .. and I didn't even try. Perhaps an impossible one? something for us to retry again and again ^^
Control of the catapult is slow with the keyboard and not very usable with the mouse. A system with the units which XP through the lvls would be a good idea too. Nice game however
Hard badge.. at last.
Some tips:
1) Priority: upgrade main cannon. Alternate with drones if your hp go under 75%.
You need to have the cannon at 4 dmg/5 rate or 5 dmg /4 rate for lvl 5. These huge carriers help for the next upg.
2) Fighters don't try to upg their dmg/hp. However go for max nb and improved rate of build.
3) To waste points in HP of the components. Generally you die faster than them.
4) turrets: For lvl 6, 1 flak max dmg range help for the mines. At added 4 lasers when i had money to spare.
At lvl 10 I had. Max main gun. Max rep. 4 fighters bays max nb, build nb 3 (ok dmg nb 1. for 10 points...) 4 lasers max upg, 1 flak max.
I liked the game.
Upgrade all the stas to the max and it's somehow easy to reach the 150k. (I can't believe there are people who can go up to 2'000'000'000. not the difficulty, juste the 10 hours to stay on the game.)
