Nice game! Reminds me of Croc: Legend of the gobbos, but I doubt you've heard of that esoteric game. Making a 3D game for metroidvania month was a bit of a gamble since most metroidvanias tend to be two dimensional. I think the non-linear paths you can take through the game (whether intentional or not) really make it feel like a metroidvania despite the game's lack of bosses and enemies (there are only bats and bombs). You might want to fix some of the animations and missing sound effects if you want to release it as a finished game, but with the time given its a pretty darn good game.

Yeah, animations are broken, but i just decided that they don't break the game so i did not fix that, and focused on other stuff, but it does ruin the effect;)
I actually just wanted to make a proper 3d platformer, and instead of going into the usual collectathon, just aim for metroidvania. So I looked mostly at Rayman 2(the rope/hook), Banjo Kazooie (dialogues, puzzles, models), Kao the Kangaroo and yes, Croc/Croc 2 (for character design). I even have physical pc version of croc 2, though the big box was thrown away;)
I had one more world in my notes, but just would not finish it, so with many ideas scrapped its very bare boned. I really underestimated the effort for even making the 3d map, which is just simple poligons, but then tuning it, and making it correct, texture, etc. all takes time eh. And yeah, i guess making interconnected dungeon like map in 3d will almost instantly make a metroidvania-like game, because its all about exploration and honestly its much better served in 3d than in 2d. Though the 2d don't get people so lost;)
