Well, it took much longer than I expected, mostly due to real-life issues.
The main features for this release are bonuses (health and upgrade points), explosive barrels and new rooms which make levels more varied.
I wanted to add more enemies, but I found the collision system to be quite buggy, especially in object-to-object collisions. So I rewrote it from scratch. The new collision system doesn’t distinguish between the level voxels and objects/characters, and it’s much faster. It’ll make adding destructible bosses much easier too. So, I decided to release it now as is, and add more enemies in the next version.
