Note: It took some time for me to get back around to finishing comments on the jam games. Pardon the late comment!
The game is extremely good all around! The pixel style reminds me somewhat of an RPG-themed Kirby boss, and the music adds to that in a fun way. Sanae's own commentary was a cute addition as well.
The gameplay itself takes a moment to figure out - and then gets good with trying to entertain the player. I really liked the idea of essentially DM'ing for Sanae. It felt like it teaches the player how much goes into making foes that behave in fun ways - and how even the most standard turn-based RPG formula is made good in the right conditions.
Overall, it's a very fun concept that I enjoyed playing the entire way through!
