Not that hopeful but let's give it another try

Platform(s): Old mobile .jar game (so not android)

Genre: 2D platformer (no side scrolling or top down. Single map like some old 2d bomberman

Estimated year of release: Before 2010? around when Nokias were still big

Graphics/art style: Grim cave style like this Image i found but much much better graphics from what i recall. I believe it had 14-15 or 24-25 levels in total and going to next level (or exiting level?) gave a shutter closing like animation (shutters came from top and bottom) where i believe the shutters were yellow-ish kinda reminding of fallout feel

Notable characters: First the main character which I believe looked like a miniature character with a skull (could be wrong). Also, one or two of later levels had an antagonist NPC, looked same as main character but pink/reddish eyes or body and would attack us or something.

Notable gameplay mechanics: Push rocks (or something similar) out of the way in the proper way in order to reach the end, i believe gravity was involved and rocks/obstacles could also fall

Other details: nothing as of yet. I dont have much hopes since it's a .jar game but any guesses would be appreciated, thankyou!

​

Edit: Some flash games that remind me of the gameplay are Aqua Energizer or Shove it, though Aqua Energizer was slightly different since u had to dig sand in it too and that i dont remember shove it's gameplay much

Summary:

• Shoving rocks in-game

• Few later levels had doppelganger antag but was reddish. You could ignore them or eliminate by dropping a boulder over them or trapping them using boulders

• Loading screens had yellow fallout vibe bars or something

• Levels perhaps had doors as well

• Rocks were affected by gravity

• Maybe 14-15 or 24-25 levels in total

• Attached image is very misleading to what the game actually looked like

• Objective wasn't to collect stuff, but to reach the winning spot in the level
