This game was a blast! I only (barely) made it past level 4-1 before my own inadequacies with timed puzzle games got to me 😅 But I did have a lot of fun with it!
It's possible I didn't play far enough, but I was sad there wasn't a point in my playtime that I could spend my hard earned gold on something. Powerups, skills, etc. But I know goblins collect gold just to collect gold, so my guess is that was a design choice, which is totally fair.
I also didn't notice until around level 4 or so that if you die after collecting gold, you lose all that gold from the level. It could be nice to either have the gold respawn or maybe you just lose like half your collected gold or something like that if you die.
Lastly, I think the only potential bug I found while playing was on level 4-1. Up at the top of the level, the walls to the side of the key could be walked through. Might be a pathing bug, or maybe that was intentional and I missed something.
Overall, despite how bad I am at games like this, I'd give it ⭐⭐⭐⭐⭐!!
