As far as day 20 goes, look at these topics:

For barbarian hoard:
1- get the gems and tech (get the oar-things latter, wastes energy)
2- pause the game, and decide where you want to build hold points. the attached image shows where i build the hold spots, but they can be anywhere within reason. However, do build a few(like1-3) walls to buy time building blasters. Dig out the area a little behind the wall(s) to fit blasters close together, giving a better line-of-sight. Un-pause when you know what your going to do. you'll want 4 blasters on the top-middle, and 5 on the bottom.
3- upgrade range and fire rate with the tech
4- you should be almost out of Chrystal energy by this point. build reactors-  lotsa reactors.. put off digging till you have enough reactors to sustain the blasters you have. After that- dig and develop the area behind the hold points. i think you can take it from there.
-side note- you are going to need to add like 2 more blasters to the bottom, don't put off doing that too long
good luck

thanks for the help i like to build up my defenses and last time i got over run with drones on bottem layer with 6 blasters.

For bonus 8 I recommend picking -20% unit cost with the first technytes, and weapon fire rate with the second - the fire rate is quite helpful to deal with the drones since you have to fight them in tight spaces (weapon range might be an option too - fire rate is better if you play optimally but weapon range leaves more room for error). Use shields to deal with any of the early drones, and build a creeper maker on the top and bottom on 4x production - once the creeper floods enough area on the top and bottom switch to 1x production and these creeper makers will be able to hold off all the drones on those lanes single handedly, and then build up blasters in the middle and dig towards the top and bottom from the middle once you want to go for the other lanes (it's much easier to advance on the middle than either of the other lanes).

what i did was fight my way to the point when the two bottom lines get close.  then i built a choke point there.  it took a couple tries, but once you get there its easy to just slog through.

Glad you were able to pull that off. Always feels good to beat challenging levels.
