Its crazy that this is developed in C only, I always wanted to try making a game just with C, since it has to be really satisfying (and stressful) building something from the ground up. I like the concept and your implementation, it looks good and is simple to understand. The levels feel rewarding, even if there are only a few. What is kinda annoying is that you cant iterate on a setup, since every time you fail it gets reset to default so you have to change the particles again. Overall, nice game!
