Overall I really liked Kyrgyzstan. Definitely a simpler kind of place but just well enough developed to feel comfortable. Amazing opportunities for hiking if you're comfortable just making up you own route with no trail to follow.
That said, experiences can vary, especially for visitors. In the capital, Bishkek, tourists might unfortunately encounter opportunistic behavior. There have been instances where police officers have been known to stop foreigners and effectively extort money. This is a serious issue and something visitors should be aware of.
On the other hand, the country offers incredibly unique and positive experiences, especially when you get out into nature. I have vivid memories of hiking in places like Ala Archa National Park. You can be trekking through a valley, thinking you're completely alone, and then stumble upon a traditional nomadic family spending their summer there. These encounters feel worlds away from anything I've experienced in Western countries. I recall one time offering to buy kumis (a traditional fermented mare's milk drink) from a nomad, and he genuinely refused to take any money for it, simply offering it as a gesture of hospitality. These moments highlight a different, very memorable side of Kyrgyzstan."
