Really nice game. The assets were really well used and nothing seems to be out of ordinary ( in some cases, some assets may not look well together, but this game was well made based on how many assets it uses).
Even if I want to praise the game, I saw some problems with some levels (especially the last level).
But first things first... What problem I had when I wanted to play the game.
1.On the game's page, the first thing I noticed was the screen that was too enlarged compared to my screen, this problem made me click for a while the "Fit screen button", but in the end I was able to do it
2.The UI of the game looks good and all, but I really had a problem with the mouse. It is nice to see a new look for the mouse, but I found it difficult for me to click on the sliders that work with the sounds (really great option btw). Also, it felt like the mouse was covering a bug part of my screen (it may make harder to see enemies).
3.In the last level, I unlocked a door that led to a giant boss, but I didn't felt like fighting it (number 4 will explain why) so I let him be. Here I need to tell the truth and say that I exploited a bug where the boss couldn't touch me if I was close to the arena entrance so I hit him with my sword until I killed him. Also, while the boss was trying to get me, all the level started shaking and it kept doing it for about 3 minutes (don't know why)
4.UI or script problem... After a while I was out of bullets, I saw an item with bullets and when I got it and tried to reload my weapon, the UI said I have "0/30", but didn't let me use those 30 bullets to reloads, and when I got bullets for it again, it let "0/30", but this time it reloaded my gun, but it said "30/30" and when I used all may 30 bullets and tried to reload (it showed "0/30") the gun didn't reload.
5.I didn't find any place in-game that told me what the controls are (that's where some players may look first)...
So that what I observed during my gameplay. I feel bad that I cant really show proof, but these bugs may not even happen if maybe other players played it differently ( I exploited a bug so maybe that crashed the game).
