Kinda felt as though I was an 8-bit Indiana Jones, which is a pretty good level of thematic immersion for such simple mechanics and graphics. I say simple, but I think some of the intentionality behind the mechanics was pretty clever and subtle.
What stuck out to me is how natural the movement, clinging, jumping, and even dying all felt. I liked the somewhat "floaty feel", and it made playing over and over on the same level pretty enjoyable no matter how many times I made dumb mistakes and died.
The art was simple, direct, effective. It did it's job without getting in the way.
If I had to provide any criticism, which is difficult and maybe even a stretch, it's that I'd be interested to see the temple setting change slowly over time so that your only variable from level to level wasn't just the layout itself. I think with that idea would come the idea that perhaps the music, while good, did get somewhat repetitive and could theoretically change little by little with the backdrop.
Nice game, look forward to seeing more from you.
