The Estonia international, 21, has only scored twice this season after notching nine in five months for the Steelmen after signing from Finnish club RoPS last January.
However, this term the Well forward is second only to Inverness's Aaron Doran with nine assists in the SPL, an aspect of his game he believes has improved markedly since coming to Scotland.
"I am very happy with the way things have gone this season," Ojamaa told Press Association Sport.
"It is all about improvement for me and the things I am working on, my movement with the ball, running at defences and trying to make things happen, are coming off.
"I can see that with the amount of assists I have had this season by running past players and squaring it, mostly to Higgy (Michael Higdon).
"Obviously it has to be continuously worked on but it is one part of my game that has improved and I am really happy with that."
