decent execution, was clever how the different sized slimes interacted with the stage. I would have liked if the bullet bouncing was rewarded more by resetting the slime invulnerability; dunno if that would have made it too easy. Unfortunately the game softlocked for me at the end of the third stage.

There is no invulnerability time on the slime. The effect is just here to show to the players that they hit the slime.
In fact the slime take damage each time the bullet is hitting the slime. So if the bullet get stuck in the slime it won't deal damage to it. The bullet needs to get out of the slime hit box to deal damage again.
