Really interesting start, the autofire spore is evil.
My tips for this one (I fear some may need a few as the start is quite devilish!)
Spoiler
Before you start set all guppies to 'stop supply' and use them for additional power, just land them in and around your base. You can then set up and move all your units, build a few relays, a few sprayers and a load of beams before hitting the pause button. If you do this right you should be totally safe within about 30 seconds.
Remember that mortars are way more energy efficient than cannons
The PZ with a shield on it looks way better with a reactor on it!
The corners are not actually that powerful
Use most early aether for power upgrades
Really enjoyed the map :D
