This game looks really nice. And you can jump, and dash, and slash a sword. The way the sprites work is really cool. The twist ending got me laughing.
But... here comes my critique:
1. So many cutscenes! I think switching some of them to more enviromental storytelling would make the message stronger. Especially at the end, where something sad happens. I think it would be sadder if we interacted with the thing that was hurt more (I couldn't make out what or who it was, but I think the moment was supposed to be sad. I assumed it was my dog.).
2. Add feature to change the keybinds. Or at least take the dash off the left shift. I couldn't use it too much, because my PC would produce a pop-up if I press left shift too many times in a row.
3. Although the sprites are really cool, the difference in animation style between protagonist and the npc sprites is a bit jarring. It would be a good idea to make them consistent.
4. It would be nice to have more content. I know, I know, this is a game for a game jam. But you have so many different mechanics here, but not much to do with them! I suppose a critique that there is not enough of a game can be treated as a compliment of some sort.
