Major changes:

• Leaderboard added (Yaaay! Never added an online leaderboard before to any of my games :D)
• Enemy count capped to 60 for spawned enemies at the same time - for performance reasons
• Bigger jump
• Handy Hand enemies (the walking hands with 1 HP) has now a greater attack range and a bit modified attack to make them actually a least a bit dangerous in the long run
• Volume of music compared to SFX is a bit more balanced now
• Checkbox settings for enabling/disabling music and sfx in the main menu
• Damage indication on the HUD
• Smaller screenshake in case of repeated shooting
• Some HUD improvements

Not so good:

• Performance problems in web export
