My game has been completed. Friends who are interested can download the trial version first. Friends who want to support me can also purchase the official version at Itch for $5.
This is a side-scrolling action game with inflation elements. You can play it if you like.

There are four major levels in the game, and each level will have a short plot performance.
After passing the level, you can unlock the gallery and a hidden character.
The game is very simple, hope you can enjoy it.
I'm also considering putting it on Steam.
