Not too shabby as a Pico's School clone: got some interesting point-and-click adventure aspects along with some neat combat scenarios, but at the moment it's definitely a bit rough around the edges.
In terms of feedback, here's what I could see:
1) Would love if there was some more interactions in the world beyond just clicking directions and inventory items. For example, it'd be great to click on BF or Tankman and get some dialogue from them, or get some hints by clicking on their locks to see what item you might need, and just flavor text in general would be nice.
2) I feel like the buttons and interactables in the world should glow/highlight when you hover over them.
3) Weird game layout where you go east and then the directions are reversed on the next screen?
4) HUD, text, and other elements aren't consistent and it's confusing. For example, you've got a sectioned health bar normally, but suddenly in the boss fight you've got a different health bar in a different place on the screen. Buttons and text change from scene to scene for some reason instead of staying the same, leading to a slightly hacky unprofessional look.
4) Boss fight and hide/ambush felt a little bit too simple and awkward at the moment: you barely have any time to read how the hide/ambush system works and the boss fight is a simple mashing race against time. Basically, not much strategy to them.
5) Transitions can be a bit wonky: people who you've killed show up for a second while you're transitioning only for them to go away once it's complete.
6) Felt it makes more sense to click on the object that needs the item instead of the item themselves (or maybe you should be able to click on either one, or maybe drag the item to the object it needs to be used on?)
7) Picking up items was so sudden and I had no idea what I got and where it was needed.
8) Boss fight dialogue is difficult to read: could maybe stand to use a text box around it or something else to increase readability.
Looking forward to seeing the full version of this game!
