I have a question how did you make the triangular-shaped trail coming from the player? Whenever I try to make a trail for a game object it's usually just square.

good idea, the only problem I accrued is the enemy is keep spawning and keep blocking my path, you should just destroy it when it was too far from the player or just limit the enemy that can spawn.

Yo what did you smoke when came up with this? Also is there sounds in the game? if there is then cant hear them

Cool idea and could be really fun, especially like that you can't shoot when carrying batteries. But the enemies spawn so close to you it's really hard to move and the repeating prologue makes retrying a bit frustrating. If these little issues were fixed I'd really enjoy it tho!
