An incredibly well-defined and crafted game that requires a bit of a learning curve when playing solo. Due to the nature of controlling both the WASD and the arrow keys for each character. But it will be a lot more fun playing in co-op since only one person gets to man each control.
Each particular action you take will influence both the heroism and the potential you get. Earning potential or not will influence the different Harold endings. And skewing your heroism to villainy and saint can be a puzzle in and of itself, also shifting your Harold endings. I got the Magic Scout Harold the first time, but I tried hard to get all 6 of them with Scumbag Harold being one of the hardest ones I try to get in my playthrough.
Getting all 6 Harold Endings can take a bit of a balancing act between acting out which particular thing and you can't pause in between a lot of the runs. However, you are given some short period of leeway to position your two controllable characters before starting. In a sense, this game is designed to be like those arcade-style mission minigames that are quite fun to play and allows for replay value.
The story itself is interesting, simplistic yet also hilarious to a degree, to which I will not spoil here for the moment to ensure other players enjoy the ride.
Once again, an excellent entry that truly allows for interactivity and fun on a gameplay spectrum the likes of which you have refined over your many game jam projects. Truly a Harold simulator of epic proportions.
