a decent game, I like how the opening animation starts, The sound design is really nice, The story? Idk wtf going on, but what do I know, I never play Shattered or any of your other games.
I didn't really bother to read every dialogue though sorry,
Now I'll say something about dialogue and menu UI, listen here no offense But it alone just makes the whole game looks impolish and not fit with the rest, I don't know if this is an intended style because I have seen you used them in other game too, It just feels out of place. Idk It felt like a default Unity panel, You should at least make some panel graphic or something that fits your ms paint art style.
Now to the gameplay, it's pretty fun, I really like the text to speech voice in the game, And the music.
The tutorial is a bit of an info dump but at least I can open them in battle.
The three ability is neat, although I usually used Wave ability because It would just end the battle almost instantly(except final boss).
I fail to see much use of Drain through since just leaving the battle for a short amount of time would heal you to full health anyway.
If you gonna add a healing ability that drains health from the enemy maybe makes the health system more punishing, something like how you couldn't regenerate at all, that would make the ability really rewarding. and maybe create a high-risk high reward situation.
the ending/story? no comment, idk the context.
Conclusion : Well it's a fun short game,
P.S : the amount of time you mentioned "Shattered 2" in comment, discord is starting to ticks me off, but well, whatever can spread your game name I guess.
