Challenge completed
Wow, I actually finished it. I actually planned ahead and somewhat stuck to a schedule.
When I saw the Construct 3 offer I decided to try and make a game using the engine, an engine I had never used before. I'm happy with the end result, but with more familiarity with the engine, I could have done something better.
I took a lot of advice from this video, so thanks to @adamcyounis for the great tips.
Lessons learned:
If you are more comfortable with coding, code. Drag and drop and "No code" engines are very useful, but if you are not accustomed to them, they can be annoying.
Asset making can be fun, but don't focus too much on details that will hardly be noticed.
Implement thigs progressively, don't obsess over small details before finishing the core gameplay.
Anyway, It was a really fun experience. Looking forward to playing what you all have created too.
