1. The dash feels pretty good. It seems natural and I think the distance the player travels is good. I think it does make the gameplay a bit easy because you can just dash through enemies and ignore them. During my first play through I just dashed through all of the enemies until I couldn't go any further. Either having smarter enemies or a limit to how often you can dash might help with this. Alternatively you could have a class of enemies that you can't dash through which might force the player to have different strategies depending on the enemy (like in Crash Bandicoot) or allow the enemies to "block" you from dashing through.
2. The enemies feel very static and aren't too difficult to kill/evade. I feel like having more enemies that are more difficult would make the game more fun. The health for the enemies is a good amount if they are going to heal. If the player can't heal then it might feel unfair that the enemies heal though. Having multiple enemies on the same level felt like a good amount but they felt very lifeless so it wasn't hard to dash through them or kill them. Having abilities or different actions/behaviors for the enemies might help with increasing difficulty. I think if it is challenging to pass a certain level then it will be more important to have to learn skills like parry/block/heavy attacks and timing them properly. Currently I just spammed the mouse and didn't bother blocking or using the parry or heavy attack.
3. I think overall the game is balanced in the way the player moves and deals damage. I think the enemies are well balanced too regarding their health and speed. To make the game more challenging and to be more fun, it might be worthwhile looking into having a key or something that the player needs to collect on each level before they can advance. This could force the player to have to actually fight enemies (if the key is a droppable item) or destroy the boxes in the level. Otherwise there isn't really a need to fight the enemies. Alternatively increasing the difficulty and the amount of each enemy can make the game feel more like a run-and-gun where the player can choose to stay and fight or try to just keep going without dying.
Overall, great job! Everything is coming together really nicely and it feels like a solid game. I really liked the way the player travels between levels. Since the backgrounds are the same it doesn't feel like you went to a new level though. This could possibly be fixed by having the level be a different tint/color or having an indicator on screen to show which level you are on (especially since you can go back down to other levels). As a side note, the transitions for the door didn't cover the entire screen and it was just a rectangle over the door (I played on a very wide monitor). I look forward to seeing the final product!
