Your progress on the game sounds impressive, especially completing level one and having level two and three maps ready. It's great to hear how focused and efficient your team has been. Transitioning into using external resources for level art is a significant step and, despite the challenges you faced, such as the issue with importing models without materials, it sounds like you've adapted well by creating your own materials. This kind of problem-solving is invaluable in game development.
For future work, considering your newfound experience with external assets and adjusting to unforeseen challenges, do you have any strategies in mind for streamlining the asset integration process? Also, how do you plan to maintain the thematic consistency in levels two and three, given the dark and slightly horror-themed ambiance you've established in level one? Balancing the aesthetic and thematic elements across different levels can be quite challenging but also crucial for immersive gameplay.
Lastly, on deciding whether to keep level three, it might be worth considering player feedback from the first two levels if time allows. Early testing could provide insights into how players perceive the game's pacing and difficulty, which could inform your decision on including or modifying level three.
Keep up the great work, and I'm looking forward to seeing how your game develops!
