Thanks for playing! I was afraid other people were going to think of the Dinosaur Game, because it's the first one that came to mind when thinking about "jumping games".
I think there's something wrong with the dog's physics model. Maybe it's too small, or the sprite is drawn in a place different than the model. I keep falling through it.
Nice game! It is quite hard, as you said, and sometimes you can fall all the way to the bottom.
The music really helps create a nice ambience, and the pixel art graphics is nice.
As for the input, I think the player should be more centered, to allow for more mouse movement. And it seems that only clicks near the player are accepted, ignoring those that are too far. Sometimes the game didn't register the input because of that.
Minicraft+ has a lot of additional features. Adding them wouldn't be impossible, but it would take quite some time to get right.
To make this demake I had to learn how to program the GBA, and plan a lot of things beforehand (eg. the save system is made for exactly this number of tiles; adding new tiles would mean change a lot of the save system).
There is a lot of space for new entities and tools though.
As for how it was made, I had to rewrite the game from scratch.
After you enter the first underground level, you'll have to find other stairs going down to the second and then third level. Each underground level has unique characteristics and ores.
