unfortunately the hint for glimpse doesnt tell me anything I didnt know already (the name helps figure that part out), my current theory is somehow to be able to get the snow on the button without the light already shining at the moth, then melt the snow (I know how to do the latter but not the former). as for wall I feel like I know half of it, but I always end with only 3/4 buttons pressed (I'm quite certain about melting the top row except the 1st snowball)
