Impressive work pulling off an adventure game like this in a jam! Big Paper Mario vibes here, mostly because of the visuals - though the gameplay reminds me of Bug Fables, which has a very similar boomerang mechanic.
You’ve created a really pretty world to explore, but at the moment it feels like there’s not much in it. There are only a handful of NPCs, and they don’t have much to say. The puzzles, as well, are interesting, but end up feeling kind of same-y. The boomerang and time device mechanics are really janky too - often the challenge was less figuring out the solution and more executing it without the game freaking out.
Overall, great work! All it needs is a bit more to find and do in the map.
