Looks good, reminds me a lot of Burntime. I found that after a few minutes it stops responding to all keyboard input so I need to kill it. Playing in DOSBox Staging.
Burntime was actually an inspiration for the development of this game :-) We tested the game on real hardware running Ms-Dos and in Dosbox 0.74-3 without encountering such an issue. Maybe you can try it in classic Dosbox?
