I played the browser version, not the downloaded version, so I'm not sure if that would have made a difference. The game felt a bit laggy/not smooth through most of my playthrough. I adjusted my refresh rate in settings to 120, and later unlimited. I also set my resolution to match my monitor's resolution, but it still had laggy moments. I have a high-speed, wired connection, so not sure if it's on itch's side or what 🤷♂️
Overall, I like what's going on. It reminded me a bit of Jump King, which I have seen be played before. The controls were a bit touchy, but I managed fairly well. Made it to the 8th level of the first climb, but didnt finish it. The different merchants are quite cute. The rewards for challenges is a great way to keep players playing and getting better gear.
