Ok this took quite a while and a lot of confusion but I finished it. What does unlocking the safe do? I did it just in case but I couldn't figure out what it actually did.
Definitely needs a hint system. Here's some hints for anyone that needs them (SPOILERS):
1. the colour of the little square things you put in the tv matter. This leads to the safe. Pay attention to the letter on the safe.
2. There is an appliance to melt the ice off the train. Sometimes it took a few tries for it to work for me. Just keep hitting E and moving slightly. Then come back in a bit.(I have a slight theory that cracking the safe is what activates the appliance? But I'm not sure)
3. The key unlocks a door
4. Fixed the sink? Do you have something that you can fill with water? There's an area outside that looks like it might need some water.
5. Used the watering can? One spot is different than the others. You have another tool for this.
6. Figure out which spot is different, then reset, then complete the game on the next run. To save time, just do the train and get the shovel. Ignore everything else.
Anyways, it was kinda fun at least! But still confusing. Like what's the point of the 2 extra squares that go in the TV? Why is there a gun in the safe?
Also having to run back and forth with the watering can is just tedious and annoying. Maybe make it so that filling it once will at least last for one row of flowers. And it's rlly easy to accidentally drop the watering can through the wall behind the sink and then have to run outside to grab it.
Nice graphics though! Interesting game :)
