After like 10 minutes I started to get the hang of it. Super tough level design & mechanic but it was actually surprisingly rewarding to figure it out! It's a very unique mechanic, turned out to be kind of like a rhythm game for me. Training my brain that pressing A means moving left but also shooting to the right was tricky. I got stuck on the "good luck soldier" level @ like 25 minutes lol. Would've been cool to see the time limit/hourglass mechanic be integrated better, I assumed it would be some big deal to run out of time, instead it just felt like an extra mandatory checkpoint reset every 5 minutes (although if I got fully reset to the start every time I probably wouldn't have played as long, maybe some middle ground?) Solid work!
