Really clever concept and fantastic level design! I had a lot of fun playing through the tutorial stages of Navigator and was a bit sad when I realized that I’d reached the end. The puzzles here are just the right amount of difficult and it was really rewarding to see everything come together to complete a stage. In particular, I really like that you have to both think ahead and react quickly in the moment--not a combination that you see too often in puzzle games like this, so I appreciated the creativity here. It was also interesting to read about your process making this game. I definitely respect that you invested time into making it easy and efficient to create new levels in the future.
Per the UI, I think it’d be nice to allow players to click on tiles they want to drop instead of just cycling through with the spacebar, especially since the mouse is already being used to place tiles on the map. Additionally, I would suggest not removing all of the placed tiles by default when restarting a level and instead just have resetting the map linked to an optional button to be clicked whenever. There were a few times when I forgot to place a particular tile or didn’t react in time during the run, then had to place everything back down again afterward.
This was a lot of fun to play and there’s definitely a ton of potential with this game, so I hope you do continue development! I’d love to play more levels in the future. Best of luck and thanks for sharing!
