Hello!
I liked the concept, it reminded me of like a 3d abes odyssey style mechanic.
I really like the art style too, I couldn't put my finger on the inspiration but it definitely felt familiar and fun.
The player controls were pretty straightforward! I'd kill for a mouse sensitivity option and mouse locking but otherwise it all operated as i expected for the most part.
Personally, i felt the enemies weren't really impactful enough, i was able to collect all the civilians in the first and second levels without actually needing to use the shield/reflect mechanic. This resulted in the gameplay essentially being an explore/collectathon, rather than a combat/protect challenge, but if that's what you're going for that's cool too, but in that case i think there's definitely room for environmental puzzles :)
Also, I appreciated the fact that it was possible to change resolutions and volume of the game in the options, these are often neglected but nice features.
