Thanks for playing and your feedback. It's really appreciated. Agree for the join mechanic, there is a trigger collider, your are limited in number, but you are right, it can be tricky. This was my first shoot'em up, and 48h was really too short for me, but a great experience. I plan to work a bit more on it, to fix the progression issue, and above all, make it the game we have in mind, and make the most of the core gameplay.
