Not bad for a first game! It even has keybindings. My primary suggestion is to always grind on platforms. Getting on a platform is already difficult and then you have to remember to press a button. I think that would make it more intuitive to play. Also I'm not sure if the level is randomly generated or static. I couldn't get very far sadly.
I noticed the 'Final update' message, so perhaps you moved on to other projects. So my suggestion may be irrelevant.
Wave 163 on level 2! I'm improving :D As a suggestion to add is some indicator of when you'll be reaching your next star. I always hope I don't miss the message so I know what star I reached. If it's the same for each level, you may write it in the description.
Also, it would also be nice to somehow see your highscores! It's tracked, but I can't find anywhere to see it!
I like that I can just send 3 or 4 waves at once to speed it up. It's also fun to see so many tanks at once :)
