Context - I have not played Flea! 1
Good Stuff:
- The level design. Every room is a challenging but fair action-puzzle. Really, really good.
- The presentation. The art, the music, and the characters are all full of charm.
Meh Stuff:
- The lives. I'm a bit split on this - they do a good job of keeping tension. However, the forcing players to redo levels, levels they already understand and thus can beat fairly easily, might not be the best disincentive for bad play. Also, by giving potions to skillful players, you make the game help players who are already good at the game, while hurting players who are less skilled.
- Minor thing, but consider making the player dash regardless of whether they are moving in a direction. It rarely comes up, but when it does it makes the dash feel inconsistent.
Overall, this game is really, really good. I will definitely be checking out Flea! 1.
