Arrows/WASD to move.
Shift to run.
Space or Up Arrow to jump (hold for longer jump).
Mouse click on game to spawn blocks.

Things so far:

• Friction
• Fixed region camera
• Smooth movement camera
• Platform and velocity locked camera
• Variable jump strengths and height
• Running/walking
• Dynamic bounding block collision
• Simulated velocity
• Jumping toggle (don't allow holding jump down for multiple jumps)
• Imprecise corner jumping (allows jumping off the edge of blocks)
• Randomized terrain in multiple screens
• Block types: Pass-through blocks, damage blocks, bouncy blocks
• Block adding/removing via mouse-click
