So, the very first versions served me right to test how the flow of the game works. As you may have been following, I've been working a lot on this game without any new releases. That's because I'm redesigning the whole game based on my scope, instead of doing it on the go, which allows me to have full control of the curve of the game, in terms of damage, HP, speed of the enemies, shops and other variables.
What I mean to say with this, is that the next update will include the first 3 days of the game (basically up to the Beastman scenario). The battle formations will change a lot, since stuff like Mettaur2s in the first day has been removed. Each day will present newer enemies, and you will not see the same enemies 3 days after it (like it happens in vanilla).
Basically, the tier 3 enemies have been distributed throughout the Undernet, and the final dungeon (and the post-game dungeon). Tier 3 enemies' AI provide a good jump in difficulty compared to Tier 2, and the player will be able to see that quickly.
The final result for the project for you players should be me releasing new versions a lot more often (I'm a lot closer to finishing all of these design charts I so much needed), and a flow of the game that will be a lot more curve-y. The game will start out easy, and the difficulty will be built up, and by the mid-game you'll know the game is meant to be taken seriously (story aside ).
Thanks for the patience, and for all of the beta testers that share their interest in the project. I promise you I'm working as much as I can to get this done (remember, at least in my eyes, the modder should also be the #1 fan of the project!)
