I am very happy, that you think that. However, Pygame, which DUGA uses is technically an engine. However, here it is mostly utilized as a framework :-)
There will always be a lot more people seeing your page than downloading your game. That being said, it seems you joined itch.io 53 days ago and already have four games on your account. Perhaps the games are rushed and not polished? I looked at some of your game pages and they are not selling the game very well. I looked at Immune Warrior and I think the idea is good, but the page is very underwhelming. Make a better description, list the features of the game, put in some gifs instead of only a trailer and images. Also, find some music for your trailer, which does not have a guy saying "bensound.com" over it. And lastly, get an artist to do your graphics and your thumbnail, as your games currently look like programmer art ;-)
I hope some of it was useful.
thank you but I polished my game and I don't have a artist and can you maybe try my game(but you have to read the tutorial else you won't get it) because I think the game play is quite exciting and also the problem with that game is there are less views so that cause it to have less downloads so if you could try it out i would really appreciate it
