God healed my heart in a similar case, when I went to church, filled with hate and bitterness. It had nothing to do with people around me. I just listened to the preacher (it was an unrelated topic) and began to feel that something was gonna change. I resisted, but He insisted. It hurt when He started. It did not at all when He finished, seeing me cry. "I hate this (censored)" turned into complete peace with a bit of harmless regrets, something like "I feel great now, thank You God, it's just kinda sad she acted like this. Well, whatever."
Level up multipliers x25 and x100 seem like a trap. They enable you to click buttons which promise high level-ups regardless of you financial situation, but, of course, they do not provide them unless you have enough gold. You click "Lvl Up: x24", you lose all your gold you could spend better, and you only get like x3. Therefore, I prefer to use Lvl Up MAX, as it stays fair with me and never tries to play on my attention.
Something goes wrong, I completed beginner mode 3 times and submitted score 128 once, but it is still shown as 0 in the main menu, so I cannot proceed to other levels.
Seeing element type is description makes me sort of happy! But I still have no idea who of these real guys outside is tank, who is assassin, etc. Everyone is just "Enemy".
Here is a good approach that works for me. The entropy fo the playfield grows over time, making more convenient and proportional space for bad guys to fill, making you much trouble. You reduce the entropy by putting balloons on the playfield. Balloons provide more order in balls movement, and you get more free space to fill with other balloons. So, my solution is to breed the balls constantly and reactively, thus making the entropy stay as low as possible.
