| Demo Release, Content Soon Increase | 2023-05-04 | Finally we have our demo out, you can now test the game with two fine disciplines before deciding if you want to peruse deeper into the depths of science. On to the content, the most interesting one. If all stars align as they seem to be aligning we are about to launch a new Discipline the Clockwork Discipline. Some of you may have played our new game Clockwork Survivors and will recognize some of the ideas. Everything is however tailor made to fit the world of the Professor Scientist. As with all disciplines there is something unique about them and Clockwork might have the most different gameplay compared to all others available to them. At |
| Dimension +1 Patch 1.3.1 | 2023-04-06 | Patch Notes 1.3.1 Dimension +1 Dimension +1 Professor Scientist has gained an interest in dimensions, now he has pierced the veil to the first one and you can gain access to new components in your next runs. New and interesting dimensions are upon the horizon as well ;) Fire Modes We have unlocked fire modes for your gain, to add a teensy bit more control during your run. Now you can change fire modes even during the wave phase and time your shots well. Hell - Hell Circle speed reduced drastically. Also now resets the speed when it exits the hell circle. The massive speedup made it almost impossible to win if you had knockback. - Hell Circle |
| Suprising Workweek Twist and Future of the Professor | 2023-03-17 | This week has been a full on chaos at our small studio. For us it came out from nowhere an email dropped in my inbox stating Epic Store was letting in anyone to release their game in the same way steam was as of that moment. Cue us dropping everything we had going on to get both of our released games into an Epic ready state, luckily for us Epic on one week of hardcore working seems to be a functional and well put together environment to release games, so most things went down without a hassle. Now the week is nearing its end(work wise, still a lot of fun time left) and we have successfully posted both games as under review. Fingers crossed t |

| Patch 1.2.2a | 2022-08-25 | Bug Fixes Projectiles teleport correctly from wall to wall Projectiles now correctly only use up one teleport instead of two each time. Early Game Safety You cannot lose anymore in waves prior to 5, the enemies will be safely teleported until you dispose of them with your gun. Losing without making any ground on the test's efficacy would be quite the waste and the Professor is quite happy he gained the budget to install some enemy teleporters. |

| 1.2.0a Playstyles Patch Notes | 2022-05-04 | Patch Notes 1.2.0a Playstyles Bugfixes & Performance Improvements Numbers aren't too big. Game was chugging to a standstill with damage number size on screen growing to be too big. Flickering on monsters & projectiles. Flicker should be a thing of the past. Nerf/Fix multiply on bounce was nerfed & fixed so that it doesn't lag the game. Fire self lifetime of projectiles is capped to a significantly smaller one. Reduces lag even in high end pc's A few descriptions minorly updated. |
| Playstyles Patch 1.2.0 Going Rogue: A Festival of Persistence | 2022-05-02 | Patch Notes 1.2.0 Playstyles Disciplines Science, as all human endeavors, has been splintered into several factions who believe their way of thinking is the best. The Dr. Professor Scientist is no different albeit his faction is the belief that his methods are right no matter which he chooses to pursue. Disciplines gives you the chance to pursue all different kinds of methodologies in killing monsters. Some are widely used in monster killing weapons research, but many are simply the result of the Doctors interest. At the beginning of the game you get to choose two disciplines, one major and one minor. The major gives you access to all the com |
