I like tactical elements in games and strategy. Nice to see a bit of that in this game. Was fun to play and to try to get closer to the surface and choose the right units to win the floor and beat those heroes!
Sound effects and music would be an additions for the gameplay in the future if you expand this idea.
Did you make all the art yourself? If so, cool 💪 and it does give an unique feeling to the project.
Nice job!
