The only level which took me almost an hour was the 10th. Here are some tips:
1. Upgrades are your friends. Reactor and weapon range/rate upgrades help a lot.
2. Seems like teleports help focusing the packets. There is some algorithm distributing the packets and it seems that it prioritises the packets based on the distance. I used the teleports to focus ammo packets on my guns.
3. Build a lot of reactors. You may need to clean some space for them. The more energy you produce the more fire power you can afford.
4. Save and recycle your creepers. Use vacuum mode and shields. Avoid map edges, they leak.
Level 10 tip: to coupe with the cripper emitters and the super-drone gateway I had to REPROGRAM some of my blasters to ignore the super-drone. Overwise the blasters get distracted by it and a creeper wave eats the nullifier.
Very nice game. The sparkling magic could show on the minimap all the items i've already seen but could not reach. It's a bit frustrating to tripple check every place I already visited.
In intern mission the top door through which I came into the final room becomes blocked by intern. And I'm out of lockpicks to get out through the other one.
The worst part is the final decision. There is no way to try another ending except starting over the whole thing. Pretty good in other (unballanced a bit though). 4/5
If I have a pile of common items in my inventory, it would be ok to continue to add there even if I turn off the common items picking option. This would allow one to pick both the crafting items and the uncommon stuff.
Better than picking an attack in a fixed order would be always choosing the attack with the quickest refreshment among fatal once and the most damaging if there are no attacks able to kill the foe in one shot. The rules for the rest of actions (freeze, presence of mind etc) should be checked before attacks or when no talent-based attack was done.
