I loved the game! The game was really easy to pick up and learn thanks to intuitive tutorials/initial levels.
I really loved adding the wisps into the game, as it keeps the player engaged in the downtime while waiting for dragoons to reach a certain location/explosions to chain -- which was one of the complaints I had with the earlier levels, it felt a little boring waiting for effects to go off.
One thing I will say is that I wish there were more in regards to timing planning for shooting the chain reactions, ie perhaps exposing the explosion timer and dragoon movement speed under one common scale. Maybe I'm just really bad at this, but often times, during the shooting phase, it felt more like luck (I'd just shoot and pray the chains time correctly, since its hard for me to predict chains higher than 2 or 3). If this was the point, to have players master timing strats, then perhaps this feedback isn't useful, but the way the chain explosions portion was formatted, it felt like you were aiming moreso towards strategy.
Anyways, I loved the trophies and achievements, as a completionist I was immensely satisfied unlocking all of them! I especially loved the 7th achievement, I "accidentally" got it within the first few levels and it made me laugh :) I loved the extra touch that happened with this achievement!
