Hello Gamers,
It is I, back with another update.
First off, I have to be honest, I haven't been able to work on the game for a while. I've been busy with college assignments, and therefore just haven't had the time to work on the game.
I've gotten started doing some more programming, terrain is still the biggest problem that is holding development back, so far what's been nearly fully implemented is:
1) Player functionality (Score, Health, Physics/Movement, etc.)
2) Steam functionality (Cloud Saves, Achievements, Workshop, etc)
3) Enemy logic and parts of the first 3 bosses.
I'm still struggling getting the terrain to be a more game-level type layout, but I am getting their slowly.
With assets, Level 2's are in progress now, as are Level 3's, Level 1's is nearly complete and I recently outsourced the new version of the background from Nikhil Kumar, a freelance artist. 
I need to update the grass and ground with newer higher quality assets, and then Level 1 should be complete.
On to animation, you have probably noticed on the Steam page in the mockup screenshots (they are placeholders, dont worry), that the idle animation has received a slight update to look cleaner, this is because I'm currently redoing the animations for the character to be closer to the character's design in my WIP promotional artwork and my higher quality concept artwork. The idle animation will be remade completely later, but the run animation has recently been redone from scratch, by the freelance animator Alex A.
Assets for Boss 1 need refining and some animation, but Boss 2 has no assets made atm, but programming on it has begun regardless using placeholder sprites, a bit like greyboxing
Anyways, thanks for reading, cheers!
