It's been a while since I've made a post, so here's everything that's up with the game right now.
A few new game mechanics have been implemented. The player can now perform power slides, although it's not in 100% working condition. He should only slide a few feet, but currently you can slide indefinitely. Wall jumping has also been added. It's clunky at the moment, but it works. These two features add a lot of maneuverability and ways to dodge attacks or navigate levels.
There are now speed settings and difficulty settings. "Hard mode" just adds new, harder enemies in its current state. There are four game speeds you can play on: normal speed, 20% faster, 50% faster, and 100% faster. This should add a decent amount of replayability.
There are four levels right now, each made up of two to three rooms, plus two bosses currently. I can get through it in about ten minutes, but someone less familiar with the game might take longer. And, of course, many more levels are on the way.
Finally. there are a variety of environmental objects to make each level feel different. These include moving platforms, rotating sawblades, pitfalls, disappearing and reappearing blocks, and my favorite, blocks that make you bounce when you jump on them.
