New update!

----- new features-----

1) the game is on Android and Windows now

2) two new enemies:

- wand (heal others when destroyed)

- potion (spawn fast arrows when destroyed)

3) two new upgrades:

- shock wave (makes knockback stun enemies)

- multishot (fire multiple super lasers at once)

4) reworked the wave system at which spawns are pre-made instead of randomly generated which leads to more strategic attacks by enemies

5) upgrades and "let's go" button now have sound effects

----- bug fixes ----

1) fixed crashing when an enemy died during push back that required shielding enemies.

2) fixed shop popping up before the wave ends

3) fixed battery sounds overwrite each other
