One of my favourite games of the jam! I remember seeing some of it in the work in progress section of the btp discord!
Really love the minimalistic art style of the game as it gives the game a really clean look. The gameplay is also really clean, with the way the player character moves being very tight and responsive, overall feeling very refined. The small number of mechanics that you have developed for the game are utilised very well and lends well to players finding ways to lessen their time by utilising the mechanics in the best way possible. The timer is also a good incentive to get people to continue playing so that adds replayability which is good.
While I understand the adherence to the theme being the minimal aesthetic of the game, I don't it's a very creative use of the them but please don't take that to be a bad thing, I just think there could've been other ways you could have adhered to the theme. It could be argued that since you have a small number of mechanics, the fact they are utilised in multiple ways to create interesting platforming rather than introducing a lot of redundant features, could show less is more so there's that. Because of that, I felt I would mark down adherence to theme to 4 stars but as for the rest, 5 stars :)
It's overall a really simple but very refined platformer that I really enjoyed playing. If you end up developing it further, I looked forward to seeing where you take it as I think it could make for a very good speedrunning platformer. Great work!
