This is a very charming game!
The "Character Name" sections inserted with some funny quips is a very charming touch! Especially as the conversation took on a few different tones. (Actual Talking Cat, Not A Dream! - Inexplicable Cat, Cryptic Talking Cat, Confusing Talking Cat, etc.) all put a smile on my face as the conversation continued.
I'm still early into the game, but I am enjoying the light-hearted story so far! (Seems even omnipotent dimensional cats don't like baths. And it's been a while since I've been in a math class but Mr. Nagawa's explanations went way over my head or it might be gibberish? XD)
One thing I was thinking about, maybe it would be nice to have a time of day HUD element (Morning, Afternoon, Night, etc.).
And I've only fought the tutorial boss (Wrestler Winston), but since the game has a real-time/ ATB (Active Time Battle) system, maybe a bar that fills up showing the next time the enemy attacks would be great! (Unless it appears in future battles or I totally missed it. ^_^" )
I'll get back to it soon, but from what I've played this is already at a very polished level and this game would be something I'd buy on Steam!
Looking forward to seeing and playing more of this game!
Excellent work!
