NO ADS, NO IN-APP PURCHASES. Platformer and word guessing game handmade for mobile and tablet! Fling yourself through 4 unique worlds, unlocking abilities and creatively using stage mechanics to make it through. Test your action skills or your word guessing skills. Your new word building game. Includes an endless mode to try and make it on the leaderboard. Robots have taken everything. It's up to you - an egg - to unlock all 100 stage doors and smash the Robo-Super-Boss into bits. FEATURES - Special Cards: Abilities you collect that can only be used one time for a single level. - Boss Battles: Each world ends with a boss battle where there are no guesses - you must collect all the letters to blast them to pieces. - Endless Run: Play forever mode to try to beat the most levels in a row without losing. - Challenges: Complete the world challenges and unlock extra challenge levels to get more special cards. Hit birds, finish levels in one life and countless others. - Stage Mechanics: Each world has multiple devices: vortexes, cannons, moving platforms and many more. GAME MODES - Classic: Use your three lives to fling yourself across the levels collecting letters and guessing the word each life. - Action: No word guessing, you have to figure out what word you're spelling to decide where to launch across the screen. All action, all creative platforming. Unlocked on finishing the game in Classic mode. This is a solo hand crafted game made by Nat Russell and I'm trying to bring back what phone games were really about - buying a game for a small price and playing it. Human made - no A.I. was used in any way, ever.
