Thanks for your feedback! I do also think that the warp core is a bit underpowered, and that it's currently better used as a means of getting around faster, rather than assisting with combat. We did want to add particles when you warped, but we unfortunately didn't have enough time. The thought of knockback didn't occur to me, but that would definitely enhance the combat! Screenshake along with more ways to heal were going to be in the game originally, but we couldn't focus on it. The flamethrower's hitbox also used to be longer, but it used to be overpowered and we had to give it a major nerf before finishing up with the game. The particle accelerator (the gun with the rings around it) was designed to shoot over walls, and the beaker scientist as well, though he might have needed a nerf. Glad you enjoyed the game!
