Character Fix

Hello everyone! I was working on the character, and all the animations such as movement and the text, because that is part of the character. So the animations all went smooth, and I coded it easily. But the hard part was the text, I had text animations and text skips where you press tab to skip the text. I dont know how to do it where you press tab once it goes to the end of the text, then the second time and it skips and goes to next dialouge, so I just did it so when user presses tab it goes to next dialouge. This was hard and I had to look at my previous games to see how I did it (because it has been over a month since I was making games) and in the previous games I had to put a function in each scene, but in my game, I just put it in the character script, so that where ever the character is the text is. I was thinking my game looks so bad, and it is not professional, but I got reassurance from others that this is one of the best games I have ever made, and it is high quality. That makes me happy and gives me the motivation to continue, but there is one problem, I dont know how to continue. I have created the alien and the character, BUT I DONT KNOW WHAT TO DO NEXT!!! So I am still brainstorming but I think maybe I should add floating islands and an alien king for each world, that the user has to defeat, otherwise they go back to the start of the level and the scene resets. But anyways that is what I am doing, if you guys have any suggestions for my game, I am open to take it. Thank you!
