Two of the levels are my own original creations, while the other two are remakes of levels from different games, one of them being a Commander Keen 4 level! Today I'm releasing a new version, which has four brand new custom levels for this game. It has been more than 5 years since I created and released a level editor for this game and released my first level pack which had just two levels.

The development of CS/PVA–PA–BA hydrogels is expected to inspire a novel method for high-adhesive and high-sensing-performance wearable electronics.I'm releasing my level pack for a bit forgotten, but pretty colourful and dynamic platforming game from 1995, Vinyl Goddess from Mars. A flexible strain sensor with such high sensitivity and wide linear range simultaneously, to the best of our knowledge, has never been reported before. In addition, the hydrogel-based strain sensor demonstrated high sensitivity (gauge factor = 4.61), a wide linear strain range (up to 1000%, R 2 = 0.996), fast response time (90 ms), and good stability. Their adhesive strength was up to 527 kPa for a variety of materials, including glass, silica rubber, steel, polytetrafluoroethylene (PTFE), and skin. The synergy of phytic acid and boric acid not only improved the mechanical properties of the obtained hydrogels (1070% of fracture strain and 0.83 MPa of fracture stress), but also provided them with outstandingly strong adhesion.

Herein, chitosan/poly(vinyl alcohol) hydrogels with phytic acid (PA) and boric acid (BA) as crosslinkers (CS/PVA–PA–BA hydrogels) were fabricated. However, current flexible strain sensors fail to have wide linearity and high sensitivity simultaneously, and their adhesion is insufficient for convenient wear and precise motion monitoring.

In recent years, flexible strain sensors have attracted increasing interest, and accurate sensing and comfortable wearables are highly demanded.
