I played ver1.0.1. Overall, very fun and unique!
Only complaint is that the English localization on the UI for the controls appears as rectangles like "▯". I also wish there was an option to remove the hit markers or make them smaller, I like having to watch the enemy's reaction to getting hit to determine their status.
I think having a flashlight in addition to the laser would be nice. Also, why is the patrol rifle not available in the customization screen and only in the hard mode?
I love the feel of the movement and the gunplay, it really immerses you in the character. The audio system for tracking enemies is cool too. The gameplay loop is very satisfying.
I hope to see more in the future!
