Thank you so much for your kind comment :D
I did indeed consider the puzzle format, with several levels and a defined number of orbs to collect, but what I really needed was to finally finish a game within the imposed limit. So I limited myself to endless game modes, and if time allowed, I gave myself the possibility of breaking down the platform layout into several levels to renew the game experience a little (no spoilers here: I had the time :D).
And thanks again for the more general compliment. I have to say that by doing the trijam every week, my brain is always bubbling with ideas. And since I usually go over the time limit, I take the liberty of making some polished games. Anyway, thanks, and I look forward to seeing you here and there, in the trijam or elsewhere :D
