Just a little guide to help with the three achievements I had the most trouble figuring out and how I achieved them.

This is where I got help figuring stuff out because I just didn't know where to go with a few of the secret achievements.

Pick a level, I went with the first one.
Set difficulty to max
pick the modifier that makes invincible

In game you will notice the bar that changes colors next to the multiplier.
You will need to destroy 5 enemies of the same color in a row to complete the bar. The bar will be at 5x you will get the final kill and then it'll clear. You got it! Now do this 10 times and complete the level then the achievement will pop.
On the first level I noticed a pattern in the enemies like after the second checkpoint it seemed like there were more yellow enemies. Keep an eye out for that because you can start the bar before the checkpoint and then complete it after.

Set difficulty to max
Pick the modifier that makes you invincible.

Basically just type as fast as physically possible no need to worry about accuracy here. Since you have the invincibility your score is 0 anyways and wont count, so no worries about it being cheating. Make sure you get to the end of the level with above 100 WPM you can make sure that you are on track in the checkpoints. Even if it is low on the first one you can still get it if you boost your speed by the boss fight.

Pick a level, I went with the first one.
Set difficulty to the easiest
I used the modifier that killed you on first typo.

This one is straightforward, just type without making a mistake. If you miss an enemy it won't disrupt you. Make sure you do not get hit and that every word you type is perfect and you will get the achievement! Pretty simple but it was a stressful one.


Hope this helps and happy typing!
