I was excited by this idea, and it did not disappoint at all! I love that you forced me into thinking outside the box, making me plan ahead to set up where landmines were going to go before I ran them through, and it was really satisfying to be able to see the way through the level and execute it first try. It made me think almost as if it were a puzzle game.
The story is simple yet effective, and allows you to focus on the gameplay. Similar thing with the art, simple yet skillfully done. I also like the explosive twist at the end of the level, clearly drawing inspiration from Super Mario Bros with your game’s signature mechanics sprinkled over the top. A lot of thought has gone into this game, and you can really see that as you play through the game.
The only issue I noticed with the game were landmines getting stuck in walls, but that doesn’t seem to impact gameplay so I can understand not worrying about those too much.
I think you could turn this into a full game very easily if you wanted to post-jam, because you have a really solid starting place that just needs more content :).
Also, the song for your game fits so well, and it’s going to be stuck in my head as I fall asleep (which I will be doing very soon). Your loading screen tips are also really well written; yet another point of detail shown within this game. Very fun game, hopefully more people see it.
