As Siliconera outlined before, Mindy’s Arc has you defending Mindy after she comes under attack by hordes of demons due to entering a contract with a magical cherry blossom to see into the future.
The defense comes by way of summoning various animal and demon spirits on the lane-based battlefield to defeat the enemies. These summons don’t last long, and so you have to be quick and observant to survive.
You can capture the monsters that you defeat to employ in your defense, and in between levels you get to buy new gear, enchant items, and upgrade your summons in RPG-like levelling up segments.
Mindy’s Arc has a Survival Mode and Marathon Mode for you to unlock outside of the main game, each of which offer increased levels of challenge for you to take on and, hopefully, beat.
You can purchase Winged Sakura: Mindy’s Arc for $11.99 on Steam during its launch week discount. After that time it will go up to its normal price of $14.99.
