Tons of progress made today! First off the player can now interact with the enemies. This includes taking damage from them and defeating them. And a new enemy type was added. Another basic one, this one moves back and forth along the ground.
Also finished today were the pause and game over screens. These include a color tint effect that can be applied to the palette. And finally a goal to be placed at the end of the level and a level clear animation sequence have been created.
Tomorrow I hope to finish off the level clear sequence with some kind of ending for the jam version, then build a full level. Then hopefully I'll be able to add some music and sound effects, and maybe some extra effects like explosions for a final bit of polish before the deadline.
