I'm glad that you liked the game. I made some assets, but most of them are public domain ones from GDevelop library. And thank you for telling me for bugs :)
You should lost shield while next to the laser, but you shouldn't die then, you die when you are too close to laster without shield. As for the number of stars, I really missed that, I need to fix that.
Edit: I fixed the stars counter bug. That should be good now :)
