I was able to kick my laptop back into life by replacing bios battery and going through a long update process. I have plans to use it in music creation, but I also moved Teemu in it. I'm hoping to arrange some time for Teemu's development that way. I don't know if it will work, but it's something to try.
Some laptops have strange native resolutions like 768 pixels height. The current version of Teemu doesn't fit into that resolution. The easiest way to fix that could be shrinking the gameview. I think it's now 80x50 or something like that. Changing height to 48 or 47 fonts should fix the problem. The size of gameview can affect to gameplay in a way that if you can see enemies sooner it's easier to plan tactics. In this case the difference is likely too small to notice.
As usual the development of Teemu has been slow, much slower than I hoped. I think the main issue is the new combat system which is not yet planned. I'm not sure if I should even try to create a serious gameplay for Teemu. Maybe I could run into another direction and make everything go bananas.
