Thank you for your detailed comment and kind words!
The characters are dwarves who descend into the pit from the drill. We mentioned this in the lore notes, but unfortunately, we didn’t have time to fully reveal it due to the jam's time constraints. In the future (after the jam), we plan to expand on this through cutscenes and new bosses. We also want to make the dwarves more interactive so that each has their own personality and humor XD
Regarding the tank's hitbox, we’ll take your feedback into account and consider what can be adjusted. The UI will also be redesigned to be more user-friendly since, for now, we made a basic version and focused all our efforts on developing the bosses.
In other words, this version is just the beginning of a much bigger project :)
Thank you for playing our game and taking the time to give feedback! <3
