Overall nice job! I will say that the default mouse sensitivity is a bit high (in browser at least), but with decreasing made it bearable. I wish it were more obvious about where the entrances to the caves were; it took me a bit to figure out where I needed to go. Also the third cave was too dark, so I couldn't see basically anything, so I couldn't complete the level. I know I only pointed out negatives here, but it overall works well! Also nice music!
