I really like the aesthetics of the game but I do have some overall critics. Progress wise I reached the triple circle (Tower of Hanoi) puzzle, got frustrated a bit :) and quit. Anyhow here is some feedback:
- Since the game is about energy, you can improve on that. Currently gameplay wise - its get "energy" from somewhere and solve a 5,6,7 step puzzle that doesn't feel connected to the energy theme at all.
- Control wise I managed to quickly get the hang of it, but after a couple of minutes of play, It still didn't feel intuitive. Responsiveness wise (go in a direction, jump) it doesn't feel right.
- Also the game being above energy - reflect that on the character and control - make her faster while she has energy, give her abilities that consume energy and are part of a puzzle.
- If the game is about moving around (gets boring fast) and solving custom puzzles (puzzle challenge), improve on the ways the character is moving around. Games are supposed to be toys, and if the only thing that feels like a toy is the puzzle then the navigating part is obsolete. Improve on that.
Also - I get that the game may be in the very early stages of dev, but the fundamentals should be there first.
Sorry if I've missed out something important later on in the game, but the Tower of Hanoi puzzle felt very frustrating :)
Best of luck guys!
