Thanks for playing, appreciate the feedback! I agree, would've been a good idea to include help, maybe a little help question mark next to each board where if you mouse over, you'd get a tooltip.
Also fair point, I had the health set to 1000 at one point during testing, but that felt too short. Wished I had gone with 1500 or 2000, but at that point I just wanted to submit and go to bed haha.
