just like the thumbnail, Allison points her katana to Toriel.

Flowey is not in he game, because Undertale Yellow (closer to the original Undertale in the timeline) was already stretching canon and wasn't meant to be there, so there is no way I can let Flowey slide, as Asriel is also still alive (at least for a bit) and Alphys wasn't even born yet.

Asriel is alive at one point, just really injured from the village incident, and spreads save points around the world as his final wish before dying to wounds.

Undertale Light Blue is going to have party members. I'm thinking of some type of panda from Snowdin.

The checkpoints are going to be on the places from the original Undertale, which makes sense because Flowey comes to those places and Flowey is Asriel's dust spread on a flower and experimented on by Alphys.

All non-boss monsters are not going to be in the game, considering that quite a bit of characters weren't even in Undertale Yellow. Why? Simply because they weren't born yet.

As for the combat system, I'm thinking of something like Deltarune, with a rectangular shape. It works like, if you hit the red spot you do more damage, and the blue spot does less, kind of like this:

Welp, we've come to an end here.

Devlog ended.
