Mech Rage is a challenging game, even on normal difficulty, but it's an overall fun but short experience. You will need to plan your moves and how you approach each room in the game if you want to stay alive because enemies can easily overwhelm you as soon as you make a mistake. The good news is that even if you die, you can respawn in the same room so that you can learn from what you did wrong and carry on until the end. Some levels have minor puzzle and platforming elements, which is something I'd like to see the development team expand on for a potential sequel or even for extra content for this one.
I’m struggling to recommend this due to its length. It can be completed within an hour. Not that it's a bad hour, but there are games cut from the same cloth that boast tens or hundreds of hours of playtime from individuals, such as Enter the Gungeon or Binding of Isaac, with the roguelike features that are practically par for the course these days.
Mech Rage isn't a bad game, but it also isn't a great game. It fails to bring anything we haven't seen before to the genre. Despite not having too much variance from other top-down action shooters, Mech Rage wasn't entirely terrible but there wasn't anything that made me want to scream “Yes, come play this!”. The $9.99 price tag isn't too bad however you may want to wait for a sale to pick this one up.
