The game has been updated again with the following changes;

- Randomized the delay after enemies are stunned before they attack again (between 0.5 and 2 seconds)
- Slightly randomized the damage of weapons and explosions (+/- 25%)
- Weapons are now stronger
- Enemies are now stronger but less accurate
- Miscellaneous minor bugfixes

Hopefully it makes the game easier and more fun. Please let me know what you think in the comments :)
