Deathplane Patch Notes

Demo version 0.3.4 - April 3, 2026

• - Fixed a crash that could happen in the tutorial when using the warp back to the Main Hub.

Demo version 0.3.3 - March 26, 2026

- The tutorial now says which button to press to jump before showing the rest of the controls.

- If you press up while not standing in front of the tutorial door in the Main Hub, the game tells you to stand in front of it.

- Turning off music will tell you that the music is turned off.

Demo version 0.3.2 - March 21, 2026

• The audio slider now stops correctly at the intended values.

Demo version 0.3.1 - January 28, 2026

- Removed the checkpoint in Level 1-2 that can cause a softlock upon reopening the game.

- Adjusted the deathplane length in World 1 Hub to make it more clear that there is a secret.

- close_ini() function is now used more often. this should help with corruption on checkpoints.

 - Adjusted audio balance on the deathplane move noise and the jump noise. They are now balanced to be much quieter.

 - Made some changes to Level 1-4 to hopefully enforce the idea that you can kill the red blocks with the deathplane.

 - Attempted to fix most issues with the level doors.

 - Incorporated the fact that you can move the deathplane with the triggers into the tutorial texts.

  - This is my preferred way to play with controller and has been in the game since the demo launch but I forgor to include it in the tutorial

 - Fixed a glitch where holding multiple methods of input could sometimes cause the character to become L O N G and move at double speed.

 - Fixed a glitch where moving the deathplane while the player is in about the 300-500 x range can cause the character to shake rapidly. This was a viewport rounding error and I fixed it by literally making the room's internal camera literally one pixel longer (viewport size is unchanged so it shouldn't mess anything up). The window size is unchanged

  - You can now move the dialogue option chooser using a controller.

  - Audio can now be adjusted with the D-Pad on a controller.

  - Dialogue box sprite now uses nine splice correctly so it looks a bit better. Same with the title menu background.

- Doors no longer have the chance to send you back to the beginning. This was an unintended side effect of trying to make the doors look like Mario, so I just removed the places where "exit doors" are at because the majority of the game doesn't use them anyway.

 - This most heavily affects Level 1-3 in the demo.

- Removed the checkpoint in Level 1-2 that can cause a softlock upon reopening the game.

- Adjusted the deathplane length in World 1 Hub to make it more clear that there is a secret.

- close_ini() function is now used more often. this should help with corruption on checkpoints.

Demo version 0.2.0 - November 30, 2025 (itch.io)

- Added an additional block in the hub to let you access the tutorial later if you want

- The font is no longer unintentionally antialiased

- The game logo is now pixel-perfect on the title screen

- Added more idle animations

- Various other bug fixes

- Added descriptions for settings

- If checkpoints are disabled, your checkpoint file is not loaded

- Introduced a new save system which should work better programatically and aesthetically

 - You will have to delete your save file to load this version

- Checkpoints now have a 15 frame cooldown between saves (now saves about four times per second)

 - This should help reduce slowdown and softlocks when using checkpoints

- Added a secret and more checkpoints to the tutorial

- Fixed controller glyph display issues

- Fixed an issue where the secret in the tutorial had a messed up tutorial text.

- World Hubs now have a door that will return you to the Main Hub

- Checkpoints now have a visual indiactor for when they are saving

- Entering the Main Hub or a World Hub will save the game

- Fixed an issue where the fact that you have a key wasn't loading from a checkpoint correctly

Demo version 0.1.2 - November 8, 2025 (itch.io) November 12, 2025 (Steam)

• Fixed a crash that could occur when going too far in the Hub.

• Walls killable with a deathplane now have a minimal animation to imply as such.

Demo version 0.1.1 - November 4, 2025

- Fixed some unfinished full game stuff being available in the demo.

- You can now delete your checkpoint file directly by holding SHIFT, -, or Guide on the Settings menu.

Do note that checkpoint files from earlier versions can be loaded in newer versions of the game but not the other way around

Demo version 0.1.0 - October 30, 2025

• Added checkpoints

  • Checkpoints are represented as a cracked blue block in-game

  • Checkpoints will do a short autosave of your current level progress and save it in the file “checkp1.sav” under %LocalAppData%/dplane__active_

  • Deathplane position, player position and whether you have a key is saved

  • Checkpoints persist throughout sessions but will not be automatically loaded when you enter the level

  • Checkpoints only load once you die

  • Loading a checkpoint will not reset the level to its initial state

  • Checkpoint files can be deleted from the main menu by deleting your save file

  • You can only have one checkpoint at once; entering a new level and touching a checkpoint will erase your last one

  • Checkpoints will remain active as long as you touch them unless a deathplane is touching them

  • You can disable checkpoints from the settings menu

  • The game will slow down when touching a checkpoint; this will be addressed in the next patch
    
    

• You can no longer “kill” flags by touching them with a deathplane

  • This caused many issues, the biggest one being that when you kill a flag, the level restarts, essentially creating a point from which you can no longer move the deathplane.

• Level 1-2 now has a floor beneath the flag

• Fixed the green coins making a sound even when sound effects are off

• You can now return to the Main Hub directly from the tutorial instead of only from the menu

• Other miscellaneous changes and improvements
