That is great to hear you guys liked the game after playtesting it, and we really appreciate the feedback on the UI and readability! We'll definitely incorporate the feedback on the UI into our future updates and fixes.
Definitely agree that the tutorial needs to be reworked and moved away from the videos to an in-game tutorial.
For the main objective, we've been working on designing a task system to give some directed ideas to players as they progress through the game, but from your feedback it sounds like it would be important to build out a points system directly into the game so the player isn't surprised by the score screen at the end on their first run through.
