I'm absolutely exciting that you enjoys my game so much! Your suggestions are incredibly helpful. That attention to detail is exactly what takes a good game to the next level, and I'll be sure to set aside some time today to polish those specific points.
Regarding the brown benches: they actually started as a game mechanic. I developed several interactive elements early on—the "Nails" being the simplest among them. However, once I actually started designing the levels, I realized that the combination of just the one-way platforms, respawning blocks, and Nails was enough to support a solid 10-minute playthrough. I spent many time on those levels! I simply couldn't afford to spend more time integrating other mechanics; I had to shift my focus to polishing the game's visuals and adding environmental elements to make the scene look less barren.
So, the original benches were simplified and modified to serve purely as background props. Admittedly, I left them in a few early rooms as a subtle hint—suggesting players needed to stand on them to solve a puzzle. But you're right; it seems the hint didn't quite work as intended. It probably just stood out awkwardly.
Thank you so much again for playing the game and for all your valuable feedback!
