Yeah I was worried about that. It was one of things I wanted to add but didn't have enough time for.
If I decide to develop this further (which I am inclined to do) I am planning on added the following:
- Tutorials to introduce the player to the gameplay and the main mechanics of the game.
- Get the controls working for different input devices including key/button mapping.
- A more detailed information menu accessible from both the main and pause menus. This will have the basics on the table of nuclei that physicists use and what the various decays do. So basically a generalized primer on nuclear physics and how that game uses it.
- Levels with specific goals. For example create Boron, or create a specific isotope of a elements, or create an element without using protons. Basically put in the more puzzle elements I originally wanted. I am also thinking of splitting levels between those with puzzle elements and those with score goals.
- Variants in level layout including adding additional walls and other hazards.
- Different mechanic to collect nuclei instead of just bumping into them. Originally there was going to be a "hopper" which you needed to push nuclei into. I also had the beginnings of the effects of electromagnetism between particles and nucelli but had to not implement it due to time.
- Add in the music tracks I originally wanted to add.
- Fix the menu system. It is still kuldgy and I am not happy with it. In fact I want to refactor most of the code so the various patterns I used are more consistent.
- Add in other features such as achievements, the name of an element popping up when you create it (not just the symbol on the nucleus), larger play areas, etc. Basically get quality of life features that make the game more accessible and rewarding.
- Get better art/sound assets to give the game a nice polish. :)
