Very good entry!
The controls take some getting used to, and I wouldn't say that they were comfortable, even when I did get used to them, but not that big of a deal, overall.
There were some graphical glitches. The screen flashed green when the boss moved and deployed lasers at the same time.
The music, sounds and overall audio is very nice and fitting.
I love the art direction and the choice of palette.
The exchange mechanic was implemented in a mandatory and meaningful way, and was also feeling very good to use it as a way to dodge the lasers!
I definitely see myself playing this game if it ever gets built upon or expanded!
