Personally, I'm not usually a fan of puzzle games because I tend to find them too difficult — but yours was totally understandable, and I really enjoyed it!
I found it very creative how you used the available elements to create different challenges with such limited resources. Each level feels completely unique due to how the elements are rearranged. Pulling that off is no easy task, and I think you did it very well.
The atmosphere is really pleasant, and the music fits the vibe of the game nicely — which I believe was meant to be something more peaceful and casual. That said, I did feel the lack of some sound effects for frequent gameplay elements, like the player’s death, jumping, or an audio cue for when the goal is reached. It’s not something that breaks the experience, of course, but it could really enhance the immersion and overall player satisfaction.
The theme was well applied — even literally — using pressure as the core concept that drives the game’s sense of adrenaline. That worked really well for your idea, so I’d say you definitely nailed that aspect.
This next point might be more of a personal thing, but I found the menus to be overly large for the amount of options they contain. It doesn’t really get in the way, but it gives a sense of emptiness and a lack of visual appeal, making the interface feel a bit lifeless — even if that wasn’t the intention. Another important point: it looks like you used squares and a line in the settings menu, which could be seen as breaking the jam’s shape limitations rule.
The only thing that slightly hurt my experience was the precision of the jump and the overall player control. Sometimes it felt like the character would slide too much, and at other times it felt a bit stiff. As for the jumping mechanic, maybe consider adjusting the jump height based on how long the button is held — that might be more player-friendly for certain puzzles, like the red pentagons near the final levels.
Overall, I’d say the game has a lot of potential. With a few extra additions, this concept could easily become something more polished and complete, especially with more levels that make the most of the creativity you've already shown. One last suggestion: try exploring some color palettes that better match the mood you're aiming for, as the current one feels slightly out of harmony.
Congrats on the game, and best of luck in the jam!
