In Sketchbook you take control of 4 characters: Square, S, Heart, and Illuminati. These are all doodles drawn in some persons sketchbook and are being attacked by other drawings trying to consume their color! Each of these enemies have a color they're vulnerable to (signified by an icon of said color on top of them). Swap between the playable characters to take down enemies with your nifty paintbrush and progress through the game! You can also ink platforms with their preferred color and use them to your advantage to trap enemies or to get higher up and eliminate them quickly!

Once you defeat all of the enemies in a level, you will be able to choose one of three powerups. These range from subtle improvements (such as an increased rate of fire of the paintbrush) to game-changing overhauls (such as a wall jump)! Use these to your advantage to get as far as possible!

    Nice idea, cute graphics. I included it in my GM48: Colors are Important compilation video series, if you’d like to take a look. :)

    Love the overall look and feel of the game! A sketchbook idea for this theme is spot on. Nice work with the coloring effects and gameplay, its simple yet fun!

    Minor additions that would be nice are no duplicate power ups on the level complete screen, maybe two lives throughout a run instead of one hit kill, and different platform arrangements.

    I enjoyed it and really dig the style. Great job!

      Thank you so much for the kind words and feedback! Yeah I was planning on fixing the duplicate powerups but ran out of time. A really good suggestion though!

      I agree with adding more lives too, would make the game more lenient, and to balance it out I guess having enemies take more damage would go well with that too. I think it'd also have a good effect on the powerup choice (ex: more hearts, less hearts but more damage dealt, etc.). That's a really good suggestion!

      Again, thank you so much for the kind words!

    Awesome visuals and lots of little notebook doodle references. I appreciate the audio a lot and the variety of upgrades. I found it to be quite challenging, but the upgrades add a lot to the curve and make you feel significantly more capable of beating levels. I didn't get as far as you did conrad, but I did have fun playing. Nice entry.

      Thank you so much, glad you enjoyed it! Yeah I was considering tweaking the difficulty curve through changing spawn rates, but didn't in the end, just added more powerful powerups, so I'm glad that worked out in the game's favour! Thank you so much for the kind words :)

    Cute graphics, nice sounds and fun gameplay. Also great that the player can choose the upgrade after each level. Well done :)

    You didn't use the sound effects in a derivative manner, this is against the rules :<

      In the rules it says: "Generators, fonts, logos, brands, brushes, loops, drums and instrument samples". I interpreted this as including sound effects, since they are so short and quite simple. Hope it doesn't cause a problem though, didn't intend to break the rules :/
