Doughlings: Arcade is a brick breaking game akin to games like Arkanoid where you move your paddle across the bottom of the screen and have to bank a ball around the screen, hitting all of the bricks (or in this game, Doughlings) until your objective is met. This game plays slightly differently in that the bricks drop down on a set timer, getting lower and lower. The game is set up with 75 normal levels and 15 secret levels. You'll need to get 3 stars on all 90 levels, and then perform a ton of cumulative tasks to complete this game. Let's get started.
To start off, just play through all of the story levels, one after another, getting three stars in each level. One important thing to highlight is that points don't matter. So don't worry about your score or if you lose points, etc. All that matters is that you collect the stars in each level. Stars are in specific positions, and you have to hit them with your ball to make them drop, then make sure to grab them on the way down. Sometimes this may mean sacrificing a life to do so, but there's no point in replaying a level because you only got two stars, so do whatever you have to to collect the stars.
Along the way as you 3-star levels, you'll unlock secret levels. These are harder than normal levels so I recommend coming back to them after you beat the 75 normal levels. You'll have most upgrades at that point, making these somewhat easier.
Speaking of upgrades, as you get 3 stars on levels you'll be getting lots of potions you can use to upgrade your personas. I recommend spacing them out pretty evenly as you progress and unlock new personas. The only ones I'll highlight to NOT waste upgrades on are Smash's 3, 4, and 5 since you won't be using Smash much after the first dozen or so levels, and don't use pretty much any of the Robo upgrades because not only do you not use him often but you also don't have many opportunities to show off with him. Morpheus, Gunner, Webster, Bedrock and Spook should definitely be upgraded fully as you get them. In particular, Gunner, Bedrock and Spook can ravage the field when upgraded.
As you progress through all the levels, you'll make progress towards all of the cumulative achievements. The only ones that won't unlock by the time you finish the levels are the ones for morphing into each persona a set number of times and for showing off with each persona. So make it a point to use each transformation as it drops and to show off with each as much as possible. Either way, you'll need to grind out cumulative achievements when done.
After getting 3 stars on all 75 normal levels, it's then time to get 3 stars on the 15 secret levels. These are much more annoying than normal levels. The "Doctor Jones" achievement solution has more information on this. Once you finish getting 3 stars on all secret levels, you'll be able to fully upgrade every persona.
All that should be left at this point are cumulative achievements for transforming into and showing off as various personas. A very important thing to point out here: achievement progress increases only after you complete the level or lose all your lives. You can NOT pause the game and select to restart the level. This will lose the progress you made in that level. Here are the best levels to grind out each one:
- Smash - Level 3
- Gunner - Level 13
- Robo - Level 16
- Webster - Level 21
- Bedrock - Level 31
- Spook - Level 56
Doughlings: Arcade is a decently fun little title. Unfortunately the lag when a layer moves down can make you want to smash your controller because of the cheap deaths it gives you. With some persistence, patience, and a little luck, the completion should be readily attainable though.
