#1-18 wait.. nothing special yet
(1) Cash
You start earning cash, #20 requires cash, and #22 theres not a Y boosts a X upgrade. which is capped to 100M. Going straight to upgrade #30, you can now recover faster, which is OP, #31 uses like a support of #30.
(1.1) Buyables
Yeah, i recommend dont buying those too early since it gives just a 1.020x boost and it seems low, so thats a waste of money..
in #40 you get a massive boost. in #46 Cash boosts itself. so magically boosts #22, and #47 gives you around a 5-7x Boost of Skill. #50 Unlocks Generator, read the sign before putting, Road until #72.
(2) Multiplier
yeah, try keeping more multi since you can boost Cash by (1+multiplier), and go straight road to the #93 where are instant win, and now use everything you have even you can afk farm for #9 and you reach #100, where you get the enough skill to get your first ???
(3) [RESET] Unfailability
Yes, you unfailed, by the good way, #9 keeps, so it will be easier to recover buying the Millisecondless upgrades, #111 Makes your multiplier boost skill, i recommend farming uf for better #118 effect. #125 gives a huge jump to Cash, and #127 unlocks the Researcher.
(3.1) Research
You start with a challenge. TFIRD research, your skill gain is nerfed and when you complete the challenge, you earn a (1*Level^2)/s Research Power that serves to buy #132. #136 Unlocks another type of research, that actually squares The first research by ^2, #138 Unlocks 100 levels more to #36. #142 Adds you another research type, in #150 Unlocks the Decelerator
(4) Decelerator
You start earning Abnormal Skill , you unlock Voltage, and you finished the game until now.
