Thanks for the feedback, I'm glad you like it.
- Oops about the tooltip, I should really be more careful about copy/pasting UI elements.
- Good suggestion about notifications, I'll add it to the todo list.
- Discoverability of actions is definitely a big todo, I have a number of ways to improve on that.
- When bots are exploring a level with undiscovered tiles, the physics for sensor scanning can get quite intensive and slow things down quite a bit. I have a number of optimizations in mind for this and other processing-heavy parts of the game. I've been putting them off until later while working on the prototype.
