The mechanic was a great idea, however it feels like you could just stay underground and forage for all the hidden gems. The delay in burrowing might be intentional but could be animated better, and i think it gets stuck animating that burrowing loop if I press it not too long. Think this majorly needs some player feedback with animation/sound/juice e.g. when you defeat enemies, collect gems and die. Also some of the game can happen offscreen in the underground phase, and the z-ordering is a bit off. Cute burger enemies though!
Yes, it would be boring collecting them all aimlessly but it is possible. I'm thinking of requiring the player to gather energy to collect a gem successfully, or something to that degree, so even if you know the location, you still need to do something extra. Hopefully, something that is fun haha! Drill animation does take a bit too long at the moment, animation could be better, and I'm aware of the bug too. Sfx are all ready, just need to update the game with them and I need to fix the edges of the level being cut off from the camera along with the z order. I'm cool with the enemies looking cute (and burgery)!
