Easy to pick up - logic, puzzle, learn-to-code types.
Alright concept - seen these before but mission on Mars fits the theme well.
Cohesive design on the theme - sound, art and UI goes very well together.
Calm and Comforting BGM, natural sound effect and extra points on voice acting :)
Summary:
Game play is smooth with good execution. I have a feeling that the battery would add challenges to the later levels but with only 8 levels it didn't shine. With 50 levels, I hope it becomes "easy to pick up, hard to master"!
My humble suggestion:
At the tutorial, let the players take their time to read and understand the instructions with the UI. The text popped away too fast!
"Current Charge" of the battery should increase as player presses the "+" to indicate the changes. As budget goes down, charges go up.
Option to spend money/resource to self-repair?
Thanks for sharing. I enjoyed the game. Good job!
