The visual style was pretty cool, and I really enjoyed the level transition light flicker effect. For this being your first game, I'm extremely impressed with getting this much done within the given time. The only critiques I would have in terms of game design are to have some sort of visual indicators to make climbable surfaces stand out, or maybe using more common climbable objects like a ladder. Aside from that, I noticed the jump animation also doesn't end when you touch the ground, but I haven't tried the download version, so I don't know if it's different there. Also, the final puzzle felt a bit out of place, considering how the rest of the game expands on the puzzle mechanics of the levels before. So, I feel like it would've made more sense to end on the second last puzzle, where everything introduced in the game was used. Although with the amount of time we had in the jam, it's a bit harder to focus on level design. Overall, the atmosphere was great and brought together an interesting concept story-wise.
