Sorry, can't take it anymore.
I was inclined to give the game a free pass for all the bugs, glitches, and performance issues it had because I was having fun, but honestly, this is just too much. It's sloppy and pathetic.
Even on low quality some rooms ran at >15 fps which is completely unacceptable for a flash game with few particle effects and low resolution textures considering I have a fairly new computer.
The whole "get stuck on a chest" bug only occurred once during my playthrough, and I resolved it by going back to the title screen and reloading my last checkpoint which didn't set me back much since your items save regardless of checkpoints. However it did instill a fear of jumping onto chests within me, and considering that jumping onto chests is integral to several puzzles, this is a critical issue which should not have made it past bug testing... Which clearly never happened.
Bringing me to my final point: It is clear that this game was rushed out and never tested for whatever inane reason. If the performance issues and bugs didn't make it clear enough, I finally decided enough was enough when I saw that when purchasing a new weapon, and swinging said weapon, THE ORIGINAL SWORD SPRITE IS STILL USED FOR THE ATTACK ANIMATION.
I am giving this a 6/10 only because the story was somewhat interesting, it was fresh take on old ideas, and I did have fun despite the seemingly unlimited amount of issues with the game. However these positive do not excuse sloppy design, now or ever.
