As you probably know, the game can't load level 28 and softlocks because it cannot place 82 viruses in the stage. I thought it might be interesting to get there asap, starting from Level 20. Unfortunately there's a lot of RNG involved, especially in the levels 24-26. Sometimes the layout won't allow you to break the top virus row.

What do you think about it ?

20-28 or 0-28 sound like a lot of a fun to me.

I finally did a "run" of this :P
