I'm employed somewhere else full-time now so it took some time, but I finally got a good amount of achievements ready. I haven't drawn anything in years so I ended up doing a bunch of revisions on all of them until they looked presentable. I think I ended up drawing at a rate of 1 achievement per weekend. I'll be adding in 2 more once I get some free time, one for completing the game regardless of difficulty and another for beating a level 2 or 3 arena on the highest difficulty without missing.

I also found and fixed some glitches while implementing the achievements. More details below ↓

Additions & Changes

• Added in 8 achievements.
  

Fixes

• Fixed a glitched that prevented the last arena from being replayed if you clear the game.
  
• Fixed the checkpoint resetting when you try replaying the last stage after clearing the game.
  
• Fixed a crash caused when looking at a certain point in level 2.
