A pen platform engine with stamping*. It's also one sprite. It also includes entities. It also includes zooming. It also includes a little see into a game I may make. You can create platforms. Under the "init" custom block, add the "init - platform" custom block. You can change "game_showHitbox" default to 1 so you can see the platforms better. To create an entity, just do the same thing. You then have to code the entities code, under the "calculate - entity" custom block. There aren't really any limits, other than the 40000 maximum platforms and 28571 maximum entities. I hope it's enough. *some could argue that stamping violates the 100% pen part, so this has not been listed as 100% pen.
