Every enemy asks a different question

Five enemy design tricks, one at a time. Each one shows the same short moment twice: without the trick on the left, with it on the right. The moments loop; press Replay to start one again, or Play to take over a side.

Same little player everywhere, with the same four moves:

• ➜Shoot a low shot
• ↗Aim up a high shot
• ⤒Jump and land on top
• ▮Wall a crate that stops walkers
