Kaguya Table: The Expansion is a simple role-playing fangame, based upon the Tōhō character Kaguya Houraisan. The game involves Kaguya flipping a table repeatedly, relentlessly and endlessly, constantly doing damage to it and receiving experience points for the damage, automatically gaining a level when enough experience points are accumulated.
The player’s role is assigning the stat points that Kaguya receives after every level up, 3 points per level. These can be put into six stats: “Tactics”, “Rage” and “Neetery” which all directly increase the amount of XP gained with each table flip; “Bossiness”, which does nothing; “Impatience”, which increases the amount of points allocated to a stat with a single click; and “Hardcoreness”, which costs 10000 stat points per point, and increases the table’s damage resistance to make the XP gain slower and the game harder. Hardcoreness points can also be spent on some special, secret moves.
If the player has more experience that is needed to level up, the remaining XP is accumulated, and it can be dumped into the “Mastery” stat to buy Mastery levels. Gaining the first Mastery level costs one billion XP, and the cost doubles for every next one. The goal of the game, or at least the closest thing there is to it, is to gain 100 Mastery levels, which can be used to “Rebirth” - after each Rebirth, the game begins anew, but Kaguya is getting more and more stat points per level.
While the huge numbers thrown around above might suggest that playing the game is a years-long affair, the interesting thing is that the scale of XP gain increases very quickly. Kaguya begins off with just a couple of measly XP per flip and it takes a couple of seconds to gain a level, but a few hours in, you are raking in billions of XP per second and gaining hundreds of levels per minute.
