Using Clear Mind, research cost is dropped (in this case, 15% as I stacked it 3 times). In the research tab, no changes were made to the icons (from red to yellow) showing what I could buy. The prices were changed, just not the icons (noted against Focused Prayer research)
Some hints to prevent hating:
- keep looking in Depots for goodies (repairs). Will get more than you need in early game.
- take passengers on short flights to gain XP, level up (full repair) and unlock planes sooner.
- Once bought 4/5 markets don't use them to trade, fly around looking for "Bob" to gain huge money bonuses.
- save up for the DC-3, gives longest play before repair
- when repair needed, switch to another world while waiting.
- build circular routes - less flight certs, more paths the check depots. Fuel is cheap.
In this way I can play for hours, using less repairs than I gain (33).
frustrating if using keys to move, that mouse is needed so much to finish levels, acknowledge hints etc. n for next, r for restart, return for hint close are basic yet have been overlooked
would prefer click-move-release rather than drag-drop - hard to drag a flashing icon. also hexes a little small - could be increased perhaps 25-30%. playable enough - 3/5
