BIG step of improvement. I've been following this game since the previous version, and I'd like to give some genuine critique.
First, the pros.
- The wall jump mechanic is very much appreciated. I was able to get the hidden away coins a lot easier.
- The new varieties of enemies make the game feel more fleshed out. There is a world here.
- Boomer is actually a challenge, I felt a little nervous every time I would miss a hit!
Now, the cons and what could be fixed.
- Sometimes when I jump on an enemy, they will send me flying in a random direction, or I will take damage after killing an enemy, which is confusing since I had just killed said enemy.
- I had no idea about wall jumping until I hit level 2, so maybe signs explaining different moves would be useful too, or maybe a tutorial menu in options.
- Bootstrappers are in a different art style from the majority of the enemies, and Boomer seems a lot more crunchy/pixelated than most enemies.
- The difficulty curve of Level 1 and 2 is real, and it made the game a little hard, which is where the issue you talked about comes in, the floaty aspect. I do definitely feel the floaty part with the bouncing off of enemies, but maybe this is an engine issue? I know nothing about Godot but I feel the enemies, and ledges cause me to slip off, rather than being able to stand firmly.
All in all, looks like you got a good project in the works here. I'll be sticking around to see how it changes.
