Good job on your first game! It has a really charming aesthetic and the game design is unique and fun.
The Gameplay
The resting mechanic is a nice limitation, although I felt it was a bit slow when the turtle could only move one tile at a time. This could be counteracted by having the turn automatically finish when the turtle uses up all their moves. But, I do like the option to skip your turn strategically.
Since most of the game is controlled on the keyboard, I feel like the Next Turn feature could have a key-bind as well. It would feel quicker and more intuitive than having to switch to the mouse.
With the amount of enemies, you could try to have them move faster. The skip button was a great time-saver, but the game should feel playable without having to skip as well.
(Really nice tutorial btw. Learning the controls wasn't hard for me at all)
Graphics
The flat tiles and textures fit the game's simple top-down style perfectly.
For consistency, you could try giving the pizza a black outline, as all the other important objects have one as well (the turtle and the robots). This would help symbolize that the pizza is important as well and make it stand out from background objects which have a less defined outline.
Music & Sound Design
The music does a nice job in matching the game's charm. It's an enjoyable melody, however, it's a little short. This can cause it to feel repetitive after a while, which can be a problem since it's the main backing track. You can try to fix this by patterning the melody into multiple motifs. There's a video that goes into depth about what makes Mario music sound catchy, and it might be a valuable watch if you're interested: https://www.youtube.com/watch?v=-x1kn0-HIO8
There could be a lot more sound effects too. Interface, environment, level completion, etc. As long as they fit into the game, they will add to the feeling of immersion.
Last thing
Please take my feedback with a grain of salt and do anything you would feel help your game better. It is only my subjective opinion after all. I'm looking forward to seeing more games from you and everyone else who worked on the project!
