Thank you for trying my game and leaving feedback. Your point makes perfect sense, and it's exactly what I tried to incorporate into this type of game. From a simple arcade shooter, I tried to add a strategic component, that is, choosing which type of enemy to focus on at the beginning to collect the type of material needed for the upgrade you deem necessary to facilitate the progression, all while trying to take as little risk as possible due to limitations of movement, the short range of projectiles, and the possibility of self-destruction. Regarding the enemy projectiles, which are similar to dropped materials, I'm aware of this and will change their form as soon as possible.
