I’ve finished as well now. I found the grenades somewhat useful but the missles were my usual go to. I was tending to just the the flamethrower all the time with the fuel being free, except for the larger monsters who were invulnerable to it or moved really quickly.
Swapping the episodes around was bizarre. I suppose there is nothing saying to play 1 first but it’s the assumption. Episode 3 was over quite quickly as a result and it was a bit late for all the instructions on 3.1. I agree about 2.1 being the hardest level. I had to restart that several times. I couldn’t decide if the levels were getting better or I was just getting more used to the game as things went on. I’d need to go back but once is enough for HH I feel.
Overall, the game is OK. Music was a bit average I thought but inoffensive. The bosses were seriously uninteresting and all of them went down on the first go except the first one when I was figuring out what the game expected. We’ve not played a lot of platformers for the show but if we’ve played one that was worse, I can’t think what it was to be blunt. Earthworm Jim was a whole lot better a few months back, presumably with a massive budget and team by comparison mind you.
