It was going be full keyboard, because gonna be other minigames that need more input , i opted to fix bug in the time i have(in fact i program a basic keyboard selector for the cave, but end disabling it, because can't reach the to implement it in main, mole and gameover).
Yeah I noted to late the sizee of the screen was to big, for experience i knew i don't have enought time to fixed it and rearrange the element in each screen in special the shot-em-up(i hardcode a few thig to save time).
Thanks for the feedback in special the coins issue(is the type of thing you don't noted for being the one made it),i think i can fix that adding a icon instead of the label in the hud).
