Really cute game. I liked the minimalistic design of only needing one mechanic.
Criticism
- add a visual indicator that shows when the dash will be back up again. Since it's the only mechanic it should be clearly communicated when it's available. Also maybe some i-frames right after the dash because its hard to estimate the distance correctly and a bit frustrating when getting hit right after dashing
- I was actually stuck for a minute trying to figure out how to go through portals. I know its my bad for not reading the description but maybe add a little icon ingame for clarity
- I liked the red golem fight but I think it's a bit too hard. The damage you take is quite unforgiving and the boss is extremely tanky
- Minor bugs: The chest sprite doesn't despawn when going through a portal and the bullets during the blue golem phase don't hurt the player
