Had a good time with this! Everything wood, and wheel mechanically work perfectly, the majority of upgrades make sense, UI layout is neat, animations make sense (loving the timer, and the random face on the fire!), and the little bit of narrative from the achievements are a nice touch.
Never felt the need to buy click power, wheel durability, or firewood capacity. Maybe have the wheel take more effort to turn over time:
1. For click power, maybe have the wheel require more effort over time.
2. For wheel durability, maybe have the wheel wear over time, if the wheel breaks, game over or buy a new wheel.
3. Instead of firewood capacity, maybe auto firewood generation.
Achievements is spelt incorrectly at the bottom. Inconsistent casing in upgrades and statistics sections (majority of words start with a capital letter but not all of them. Game gets slightly dull when both infinite upgrades are bought:
a. Instead of infinite wood, infinite firewood would keep the player clicking the wood rather than watching.
OR
b. Random narrative events which disable the infinite upgrade temporarily so the player needs to keep an eye out.
Audio would have been great, especially a fireplace.
Overall, great game!
