Hi, I tried the game, here are some of my thoughts:
I like the concept of the game, with the different types of attacks with different effects. I feel that could work very well if you take this in the direction of a puzzle platformer, where you have to figure out which types of attack you need to move past the enemies.
One thing I noticed quickly is that the character always faces the direction it is moving in, rather than the direction you press. So when you are running right, and then turn left, it takes a bit for the character to also turn left. And because this determines in which direction you shoot this felt a bit wrong.
The items don't really make sense to me, e.g., tomato and chicken freezing the enemy. If there were more levels where these items returned without the explanation boxes, I would have a hard time remembering the effects.
I also tested some of the accessibility settings, it is very nice that there are so many available. The difficulty setting is great! The auto-fire is nice and works well. The auto-jump didn't always feel great. The character would jump also when you walk down a ledge, which is not needed, and there is one ledge in the 3rd level where the auto jump did not work.
The pit wind sound I found a bit hard to hear, I had to turn down the music to be able to hear it.
Lastly, I could not change the UI keybinds, is that intentional?
Good luck with your thesis!
