Very fun experience, With decent art and music. But the sounds are a bit loud at the end when all the meteors come crashing down. I also didn't realize it was a agar.io type of gameplay till I accidentally ate a crystal. but that could have just me being dumb--.
I also didn't realize that I just stayed in one section of the map until the very end where I tried to run away as far as I can from the meteors and found out that there was much more to the map than I played. The jump is not that useful until you get the speed upgrade as well.
Good job in making the game, Hope you can use these if you ever decide to polish the game.
