I'm glad to hear my feedback was useful, and honestly I am impressed that you had multiple route to most abilities. Because yes, until the wind ride ability I rarely felt like I was being locked into one specific route as I was in goat's gorge. So strictly from a design point of view the layout of your rooms felt pretty good (excluding the aforementioned thunder clouds blocking off nearly all the wind ride routes).
I will add onto a point I've seen from other users' feedback; more background details could really go a long way in fleshing out your game. For one it would give players more memorable landmarks to help with navigation, the first Zeus shrine for example stuck in my mind until the very end so I knew exactly where to go after getting teleport.
In a similar way you could even have background details allude to the direction/location of different upgrades. But overall for a month long jam, there's nothing wrong with focusing only on the barebones mechanics and level layout.
As for play time, the in-game timer says 73 minutes, however I did leave the game on in the back ground a few times when taking a break and I don't know if your game's timer ticks whilst paused. So for now I'd round it down to 60 mins, which for a jam game is a decent length of time.
A small parting note: most of my feedback here is strictly tailored towards the level design/layout of the game world, as this is what I'm currently focused on for my Mousey Tales. And honestly, I've already begun rethinking a few problem areas in my own level design based on what I've seen in meteora.
