Hi thank you for your honest feedback, the jump precision has been mentioned a couple of times and of course I will polish this part of the game when I have finished building out the first area . (so far I'm about 40% through) I try to add new parts and enemies per major build. Allot of what's on there at the moment is being iterated throughout my development and is currently on its fledgling phase so all controls will be iterated upon as I progress.
Regarding the projectile issue, personally I don t mind how it works right now as I haven't implemented the shield mod yet and this will be the defense our player needs against projectiles. Your player will also become less squishy as you progress with health boosters etc
Thank you and hope you continue to follow the progress ,
