You can make the red yellow and green balls stop falling by clicking out of the game then you click on the ball, this way it is really easy to get them. This way you won't need to get the upgrade for swiping over balls.
Here are some suggestions. 1)Reduce Lag. 2)Make it so while you are trying to make your own level you can have the option to fly or not makes it easier if you're trying to get to a point but its really hard. 3)While making an object/person talk and you press the 'm' button don't make it mute/unmute. 4)Add more item chests that cost more than 100 coins but make is so there is no chance of getting the crappy stuff up to this point if the coin chest is higher. 5) There should be two options for map type for example sometimes you are making a Story level but it is also a Battle Royale level. 6)Add a Black Hole object in the level editor, this object will suck any player in the level and coins into the Black Hole, There should be a limit of block space the Black Hole can suck also it would be cool if you could turn an option for Black Hole to only suck coins and players if you go into the Black Hole Block Limit.
It's really annoying when you're making a level and you're making a sign or a person saying something but you type the letter 'm' which mutes it or unmutes it again which is really annoying. Please make it so you can't mute/unmute if you are typing for an object/person.
