Combo Gems

Tutorial/Learning Curve - after about 10 minutes of playing I got a pretty good grasp on what the different colored gems do and how the synergise with one and another. The tutorial acted as a guide for me to piece together how it worked by myself, which is great for a certain group but most will not put this type of effort into a mobile game they've just installed. I had to keep going back into the setting and re-enabling the box prompt to remind myself what each color did what, it would have been a lot better if it just told me then and there what the colors did, instead of having to waste a game and reading it while playing.
When learning the game through the box prompts I shouldn't be able to interact witht the game while reading it, I natrually tapped the screen outside the box to trigger the next tutorial page and instead I selected a gem and wasted a turn. Having a hand crafted stage that goes through all the mechanics on everyones first game is an awesome way to counter this.

UI - At times I wished the blank space around the play area was utilsied more. Being able to open a prompt that tells me briefily what all the colors mean and different points gained from what shapes would be an awesome quality of life feature. As well as how many points I just gained form the combonation I made, making it a lot less tedious to optomise my stratergy.
Occasionally my fingers in the menu screens would press 2 buttons at once, maybe just spread them apart a bit more to prevent this.

Highscores - Having more than 10 scores saved seems kind of pointless, I only want to know what my best scores are.If possible even who, I would love to hand my mates this game and see if they can beat my highscores. Adding the classic 3 letter ID at the end of a game would be great! I can imagine some players get annoyed at having to input a 3 letter name at the end of every game so maybe adding a simple already used ID section will remove this annoyance.

Achievements - As a personal preference I like to know what it takes to comeplete an achievment. It allows me to set a goal that drives me to continue playing the game until I have completed said achievement. Currently all I have to go off of are some basic titles.

Bugs - Haven't ran into any as of yet.

Final Thoughts - Really like the mechanics and how they synergise together, the basic UI and animations are perfect. Sounds seem stock which is fine, somtimes a bit too loud or sharp for the lack of a better term. Highest score before writing this reached was 49, 524. Overall I enjoy this game a fair bit and plan to continue playing and seeing the updates. Good luck!
