Quite enjoyed this - simple but effective game loop that kept me wanting to replay! Once the upgrades start piling up it really feels great being able to power through the blocks. Attacking and hitting feels satisfying with good audio/visual feedback. Balance wise I'd say its slightly on the harder side, and by nature is quite luck based in terms of how fast you find the exit. It felt like on some runs I accrued upgrades way quicker than others. Overall nice concept and feels like it has potential should you wish to keep developing it. Good job!
