Patch Notes 1.1.4

Changes (since 1.0.28)

• ... Boss Run! (see above)
  
• Water update:
  A lot of people really liked the bucket weapons, but we felt they weren't as useful as they could be, because their ammo runs out quick. So we added "water drops". They refill your water just like the HP hearts refill your HP. Enemies have a chance of dropping them, so now you can refill your bucket by fighting enemies. This should enable a much more fun dynamic for switching between buckets / gumgum guns.
  
• Eating fruit adds a little water.
  
• Bankkrent Phase 2:
  One of the bullet attack patterns has been slowed down & altered so there's more room to maneuver through projectiles.
  
• Sinkhole no longer shakes after finishing and returning the game.
  
• Blione King has less HP.
  
• Made Bram's sound louder during the battle.
  
• Murk has been altered a bit.
  

Fixes (since 1.0.28)

• The bib fnakkers are moved to a different location if you skipped them and defeated Chef Fnaquere, rather than standing around at the food party.

Changes (since 1.0.24)

• Camera zooms out when there are giant rocks flying around. They were unnecessarily hard to dodge when the camera was zoomed in.
  
• The helper bliones are a bit easier to jump on. Also a little sound & effect got added.

• More invincibility frames after getting hit by Bankkrent or his friends and various other bosses. This might make the game a bit easier for people who were struggling with bossfights.
  
• Fnakker rocks behave a little bit different. Should be a bit easier to avoid in certain situations.
  
• Wum looks a little bit different during invincibility frames.
  
• Subtle 'fnuist' effect added to whenever a creature dies.
  
• Added sfx to the scale in Redav Kned's Guesthouse.
  
• More optimisation for final boss fight (fps boost if you had low fps there).
  
• You can now use some of the rock spikes in the background to hide from the wall crack attack during the final boss fight.
  
• Stoplight a.k.a. Traffic Light With Fists now drops 16 splenkhakker coins instead of 20 smurt.
  
• When entering the Sinkhole / Bliekopolis, after leaving your pot helmet behind (for example in the Wumgarden), without finding the new pot helmet, Denksnavel will hint towards that new pot helmet.
  
• Made the partially broken wall in the Blenktower more visually notable. It was easy to miss and that would just leave the player clueless where to go, which doesn't seem like a fun "puzzle". Also fixed that it sometimes didn't get hit properly.
  

Fixes(since 1.0.24)

• View no longer appears stretched at the final boss if you are playing on a 16:10 resolution.
  
• Credits background got fixed for 16:10 resolutions.
  
• When there's a white flash, it's no longer displaced on 16:10 resolutions.
  
• Error at Lans & Merik when using the Breft cleaning suit while walking into the room got fixed.
  
• Using the Breft suit no longer wakes up Lans & Merik.
  
• There was an issue where you could get +10 Happiness in one world when finding filmstrips, and it'd be confusing to not get +5 in the final world. Should all be fixed now. If you think the game or an update screwed you and you missed happiness from finding filmstrips, you can head over to the Allesweter. If this is the case, it should automatically get fixed.
  
• Super rare Train glitch where the collision mask disappeared and you could fall of the sides should be fixed.
  
• A Bankkrent phase 2 attack behaved a bit weird and shot mudballs towards you, but now it shoots them up in a pattern which should be easier to avoid.
  
• Fixed a bug where you could sometimes double jump again after catching food mid air.
  
• Damage numbers will no longer combine when using rapid fire weapons, I thought it looked weird.
  
• If you got hit while standing on the ground and then fell off a cliff, you can use double jump now to recover after a short delay.
  
• Some cardboard boxes in the Wumhouse had wrong collision masks. Not anymore.
  
• The Cooks Story filmstrip checked the wrong world for whether you had all filmstrips and if it'd give you happiness.

• Murk's (Café boss) bullets no longer display wrongly coloured particles.
  
• You didn't always equip your weapon after loading a savefile, fixed now.
  
• 1.0.29 Fixed a bug where you would get soft locked if you get kicked out of Berdy's room while he's standing on the pizza box and then show the Blak Cake to him.
  
• 1.0.29 Fixed a bug where you would fall out of the screen if you weren't inside the middle chamber after winning the final boss fight.

Changes (since 1.0.21)

• The CREDIT will increase much faster depending on how many jobs you tried out and whether you've figured out the kneft infestation.

• Traavis Duivels' store is 10 times as cheap.

• Fixed an issue where you could get stuck in the ritual place by moving the walls down with your instrument before entering the room.

Changes (since 1.0.20):
