This is a great concept, I think it deserves to be more developped, and why not becoming a real game !
Things I liked
- The roguelike aspect is very cool and not often seen in game jam because it take too much time to implement, good work with that
- The energy management is very fun, with different ways to see (light and radar) and you have to turn off some things to get deeper and make more points
Things you can improve in the future
- Please add a tutorial or make things more explicit for the player, it's hard to understand all information and buttons...
- Movement is too slow in my opinion, with the fact that we can only know approximately where the mine are, it's hard to avoid them
- These game could be really cool with better graphics of the animals you encounter, like discovering real species of our oceans
