Got a copy of Freedom Planet from a friend of mine on Steam, and I must say it's pretty fun! The pixel art is lovely, the voice acting ranges from functional to amusingly corny, the music,'s neat, and I really like that gameplay-wise it's not just a reskin of a Sonic game. Doing shoryukens, dive kicks and Rocket Kight-esque air dashes really spices things up, and I really like how the enemies don't cause damage just by touching you, really makes sense for a 2D game with limited field of vision where you gotta go fast.
Also found an old copy of Armed and Dangerous at a loca flea market, it's an insanely fun, crazy TPS á la MDK with ridiculous weapons and some pretty strong humor.
