Probably the slickest and sexiest game I've played all jam.
Good points:
Simple design
Animation of the Kaiju was great.
Characters, have great style: Italo, SOT and Mechani-Chan look visually developed.
It's damn fun.
THE TRAIN SOUNDS. I love how that horn is incorporated in (Spoiler?) both battle themes.
Minor Quibbles:
The shop - Maybe tool tips? Or at least labels? I had a hard time remember which car did what. And even after I found the ? screen, I still had to consult it way too often.
Lack of player interaction once the game starts. Yes, it's a set and forget Autobattler. Not sure you want to do something like morale boost or something that can affect outcome. If you don't, maybe a way to speed up a bit? Maybe I'm just impatient ;)
Either way, probably one of the best I've played this week. Thank you for that, and I'm going to take another shot at it again now.
