Very interesting game and had a lot of fun playing it. That being said, I do agree with the previous comment that...
(Spoilers)
...the fact that there's nothing that felt like an Absolute Final Thing is a little bit of a letdown. The Dark Dragon Statue or Unicorn endings are probably the closest ones, but only because you need a lot of effort to achieve them rather than any sort of narrative closure, because the end result is usually more or less the same. (After doing those two endings, I just stuck with actually using the Ending Hax Tool, lol.) Nonetheless, I still had a lot of fun playing around with different fights and seeing how things interacted.
Getting the Unicorn ending without the tool is definitely doable, but you need the right strategy and a lot of luck on your side; it took me about an hour of resets on the Birdman fight to get through because of the crows giving the Blind debuff quite often. After that I just spammed Summon Crow and got through the Imp fight fairly easily.
Thanks for playing! I'm glad to hear you enjoyed it.
...And for design mistakes you pointed out...
- For the thing being a letdown, it should be less terrible, at least for new players, in the "100_2" version, with attached txt files changed.
- (Do note that the in-game event is unchanged, so re-installing the game doesn't change the situation much.)
- Now it's noted in the "Game Over List" instead of an ominously prepared separate file.
- In the new writing, The TF scene itself is treated as the main part of the event rather than just one of the steps towards the usual game-over screen.
If it still disappoints players, let me awkwardly claim that it was an easter-egg...
- For the endings being the same, I would like to claim that this game is supposed to imitate a prologue of an ordinary RPG: a personality test to determine your class/stats (e.g. Pokémon Mystery Dungeon, Dragon Quest III). Because of this, "the personality test" has more than a few different results but "the game proper" (this game's endings) doesn't change much.
- Another, or the real, reason for the endings being the same, is that I really couldn't think of a wider variety of them. Sorry.
- Still, some of the more difficult endings could have used more gimmicks...
- At least the Ending Hax Tool had a good use, since repeating the same game many times in slightly different ways just for endings would be painful to many of the players.
- For the difficulty of that particular ending, I'll blame some person who did a low-level run of Untitled. But I believe you can defeat the Birdman without too much luck if you use magic when the sword is not an option.
