Adventure Mode - Level 7: Maze
Ship Configuration: Collect + Miner
For this achievement, it is all about geoms and speed. The spawns for the enemies will always more of less be the same, and the only dangerous waves are the ones with rapidly moving enemies or homing enemies. You get 1 bomb & 1 super. I recommend using the bomb to speed up a wave near the end, and the super can also help when running low on time. The hardest wave is the one that includes the exploding pink squares as they move quickly and explode spawning more enemies. Just focus on killing enemies, collecting geoms and staying alive. You should be able to reach 2,000,000 points eventually, and just make sure you reach the end of the level without dying. The level end when the timer runs out.
