Hi. I have finished the next part of Abandoned. It's not Abandoned 2, but spin-off. Some bridge between 1st and 2nd part. Hope you'll like it. http://www.kongregate.com/games/krutovigor/abandoned-the-cube-chambers/
Block runes + healing + cloud runes is a great combo. This creates literally indestructible obstacles. Even better if you have an AOE range rune.
Hide behind those blocks and spam spark-ranged spells --> profit!
I'm so sorry, I had an unexpected business trip, I'll need a few day to complete the update.
