Hi, I thought I give some games feedback who have low ratings. Because I think everybody should deserve to get some feedback, not only those who post their games like crazy in the community forum :D
I hope you are not angry, when I tell you that your game is not very entertaining. The graphics are ok and the controls are working. The character is not glitching through any wall or something. But I am quite sure that you put the movement code for your character in the Update instead of FixedUpdate function. This is the reason why the character is making such weird moves when you run against a wall or a corner. Maybe search youtube for "Unity fixed update".
I like that you have different kind of enemies which also need a different amount of hits. Talking about the fight system, I don't like it. It feels so weird swinging the sword around with the mouse.
I like the details you put into the character with the simple but efficient running animation. The switch of his head position is also really nice when you change the sword from the right to left or vice verca. You could have used a different sprite for the character/character head when he is running up which shows the back of his head for extra details ;)
Your music is not present and you only have one sound effect. I think you know what you have to do here. :D
Level design. Your levels are way too big and I got a little bored running around. Some times I wasn't even able to finish exploring everything, sometimes not even finding the exit because the time was too short. In addition level 1 had always the same layout, same for level 2 and 3. Didn't make it further :D You should have gone with a smaller level and maybe a faster movement speed for the player to make exploring faster.
Only having the one power up in the level makes it feel really worthless to explore. Having multiple power ups would have been cool. And I think your game idea would have even worked better this way, because then the player had to remember what he already picked up.
What would have spiced up your game would have been having procedurally generated levels. I think this is something you didn't have a look into yet. So maybe you want to check this out ;)
I hope my feedback helps you.
Maybe you stop by at our game and give it a try ;)
