A few details not in the video:

There are plans for multiple types of guns.

The combo meter (little yellow meter) can build up to 4 Charged attacks. At max, you use the electrifying screen-nuke. Otherwise, you do a crowd-control spin attack.

Heavy enemies take a bit more work to stun, much less defeat. The guy here takes four punches in a row to stun, or a powerful-enough shot. Regular bullets don't move him an inch.

Three reasons to be going after the treasure:

I made an up-to-date trailer for Terry's Treasure Trouble!

You know, in case it wasn't clear what kind of game this is.

If you've had your fill of games where you play as elephants and blue hedgehogs, this might be for you.

...and I haven't advertised this the best, but it's coming.

Cleaned up the HUD for visibility.

The background is temporary. The tiles, we'll see. I can't say I like drawing elaborate backgrounds, despite my previous game's gratuitous use of scaling BG effects.

...well... This is awkward.

Yes, I CAN make an animated background within a matte, with a shifting color palette. However, I realize this doesn't look like lava, no matter which way you shake it.

...the effect's cool, though.

Nothing is more encouraging than developing an enemy AI just right to the point where you're saying, "It's fun now!"

...and this is practically an evolution of the Shiro Ninja games.

Kinda experimenting with the background here. It might come off as a big, flat painting, though.

Should I bring back that perspective BG thing from my previous game? Or give this another BG layer?

Curse you, subpixel math and solid block interactions!

This is a common Game Maker problem when colliding into a corner in a lot of platform games. It thinks it's hitting a wall and the ground at the same time.

Edit: I think I've fixed it.
