Here's (mostly) everything I have done today:

(It required over 1,500 lines of C code. Decent amount for a single day!)

As you can see, bullets can be collected but they are not shot. The shooting will be related to the other "incompatible genre" (although one would say side-view point-n-click metroidvania is enough) I have not yet implemented.

Last time I focused on graphics, this time I focus on gameplay and the content. Let's hope I have time to implement everything (I'm doing this for compo). I might have to leave audio out of this, and add it later in a post-jam version.

EDIT: There is no lives, but if you take damage, you'll lose precious seconds!
