I made a post before which was replied to by the dev, but all the old posts were deleted and this new message board was implemented before I had a chance to see what was said. I will try to remember what I wrote and maybe add to it now that I have taken the game way beyond its current ending.
Obviously it's a little odd with the dimensions. The final mountain (so far) being a million km high, but it's just a game so that doesn't really matter. Crazy numbers come with the territory. Though it may be possible to start at mm or nanometres.
In the meditation menu, if you hover the mouse over where a hidden skill will eventually be, you can see the name of it in floating text. I don't know if this is an error or intentional.
Two of the aforementioned skills, the ones that give you a 'buy all' button give you strangely named buttons, considering. The 'Buy All Updates' button allows you to buy all upgrades, and the 'Buy All Attributes' button allows you to buy all aspects.
I had been wondering why the 'Next' upgrade limit for the aspects is 200, 100, 100, 100, 50 but after playing for far to long I have realised that you need more than 1000 Mm for a single aspect before reaching the next bonus, so this makes sense.
The game seems to be more of an incremental clicker than an idle game, but maybe that is an aspect of a planned future version, or maybe you want the people that this game is aimed at to find it more easily.
I look forward to seeing Achievements, Quests and Challenges as well as the other hidden extra. It's a shame that my save game probably won't work, but it is what it is, and it won't be too hard to get back to where I am now that I know what I'm doing.
