Pros:
- The concept is actually quite cool with the 3 different types of crystals with different effects.
- There aesthetics fit the came concept well and its fun
- The set goal of 2 mins instead of high score is a unique idea
- The tutorial and main menu is good
Suggestions
- I think I would prefer if it was from a 3rd player view as I found the controls quite difficult, but perhaps adding this challenge is part of the game design to add difficulty
- Your screen size settings are wrong and quit button breaks the game and requires it to be reloaded.
- I found the mouse settings very sensitive, perhaps its because my mouse has quite high dpi though.
Overall, good implementation of a cool concept
