Taking a break this month from creating games. I'll start thinking about ideas for the up coming Ludum Dare of course. But for April, I'm going to try and focus on messing with different tools and frameworks. I've been making stuff in Libgdx and Java, but I want to see what else is out there.
Html5 wise, I've done the most with MelonJS, which I like for many many reasons. It feels familiar, I find I can navigate around the source code quite easily. It has great tiled map support. What I do want to look into though (and already have begun) is Cocos2d. Just how the API is structured reminds me a lot of some 3d libraries I used to mess around with years ago.
I also want to look at C++ and SFML 2 for some reason. Not sure if I'll stick with it, but it's nice to see what is out there. Java definitely serves my purposes as far as performance is concerned.
To go much more high level, I have some bookmarks for learning unity, and I feel it's worth a few hours at least. While the cost of unity to get the extra features is quite high, one can make some pretty decent games for free.
Aside from that, I might toy with LWJGL a bit, and see what that is like.
My main focus here for sure is HTML5. While I do have concerns, it's hard to ignore the amazing feet that Mozilla and Unreal brought forward. If you're not sure what I'm referring to, install a nightly build of firefox, and check out: https://developer.mozilla.org/en/demos/detail/bananabread
