Level Selector, better animations, and more!

oh deltaTime, deltaTime, deltaTime...

This week I've finished polishing up the animations and added a simple level selector. The animations look really good now, and I hope that it'll be able to provide the player with feedback that feels intuitive.

I added a level selector so you can finally select which level you want to play instead of me having to load it directly from the code!

I was not able to add additional levels however, due to time constraints.

Why did I have time constraints you ask? It all happened when I tried exporting my game as a test; most of the animations were messed up. I knew instantly that there was something up with deltaTime. Well, it turns out that on the development version, I was running the game at around 400fps, which caused the deltaTime to be very small. However, in the production version, the game was fixed at 60fps, which made the deltaTime relatively much bigger. I didn't think it would be an issue but as it turns out, it had a large impact.

I didn't think that running the game in 60fps would have a large enough deltaTime to cause animation problems so I naturally blamed my poor math skills and went back to re-derive all the formulas, only to find out that (surprise!) I actually did all the derivations correctly and the problem with the animations wasn't actually my fault for once.

Then this turned into a long Wikipedia adventure to find a better numerical integration methods until I realized way too later that I could just fix the deltaTime steps at 1/400 and just... run the function multiple times. Oops?

Anyways, enough of that. In this version you should at least be able to play the game and experience the smooth animations that I worked hard to make. The main menu needs a proper texture which I'll get around making the coming week, and I still need to find some sounds to add to the project. Also, I need to finish adding the rest of the levels and finally, I need to figure out an algorithm for dropping number tiles in a way that the player doesn't get softlocked. I have a general idea of how to implement it but I'll have to see if it actually works.
