A very cute little experience. There's a lot I really liked about this. I liked how there was a little bit of unexpectedness when <spoiler> they explode if they hold tnt </spoiler>, and the art style was great all around. The humor with it was great as well, with some of the combinations being silly along with the dialog at the end. Also, this is a custom game engine? I assume it wasn't made during the jam, but that's still really cool. If I had to make one suggestion it's that this game concept really needed more possibilities for things to come up in the customization. Even with the game's short timer, you tend to see a lot of repeats, which impacts the gameplay.
My best score was 63
Also, I may have been looking around the game files, and I have to say I love the placeholder.png files:
