Add items/power-ups

[mliou]

Have items spawn that either give the player bonus points or power-ups (or maybe both). Some ideas for power-ups include higher jumps, faster speed, or invulnerability.

F16 UPDATE: Clearly, higher jumps are not necessary, but increased movement speed and invulnerability could be cool additions. Additional power-ups are up to you.

There are a lot of interesting options here. Be creative. Shields, speed boosts, shorter cooldown times, etc... are all options.

Points will be very dependent on how much effort is put in here and how much the game improves.

W18 OK (100-250 pts)
